The minimally processed industry is always looking for produce innovation that can satisfy consumer needs. Wild leafy vegetables can be a good source of bioactive compounds and can be attractive for the consumer in term of visual appearance and taste. In this work, Sisymbrium officinale (L.) Scop., commonly called hedge mustard, was grown in a greenhouse and evaluated as a potential leafy vegetable. Two wild populations, Milano (MI) and Bergamo (BG), were grown in peat substrate and harvested at the commercial stage for the minimally processing industry. Leaf pigments such as chlorophyll and carotenoids were determined as well as chlorophyll a fluorescence parameters. Total sugars, antioxidant compounds such as ascorbic acid, phenolic index, total phenols, anthocyanins, and nitrate were determined at harvest. Significant differences between wild populations were found in April with higher nitrate content in BG, 2865 mg/kg FW than in MI, 1770 mg/kg FW. The nitrate levels of S. officinale measured in the present study are significantly lower than the maximum NO₃ level allowed in other fresh leafy vegetables. Ascorbic acid measured in November was higher in MI compared BG with values of 54.4 versus 34.6 mg/100 g FW, respectively. The chlorophyll a fluorescence data showed that BG reached optimal leaf functionality faster than MI. Overall results indicated that Sisymbrium officinale (L.) Scop. can be suggested as a potential leafy vegetable for the minimally processed industry.

Number of wild edible plants is commonly used in the traditional diets of tribal people in many parts of the world. North Maharashtra is well known for its tribal region and tribes from this region partially or fully dependent on the wild resources for their nutritional requirements. The present study was designed to document specifically the wild leafy vegetables from North Maharashtra. A total of 62 traditionally used wild leafy vegetable species were collected, identified and documented. Out of 62 species, 61 species belongs to Angiosperms and 1 belong to pteridophyte. With respect to families Amaranthaceae, Araceae, Asteraceae and Fabaceae were found to be the largest families with 29 species. Herbs are the major source of wild leafy vegetables with 43 species and forest is the home for the majority of wild leafy vegetables. Due to less awareness, loss of vegetation and fast erosion of traditional knowledge many species are on the line of rarity. The study helps to conserve those wild food species and cultivate them on large scales, to uplift their economical status and sustainable management in near future.

From many years ago the tribal peoples commonly used numbers of wild leafy vegetables all over the world. Peth and Surgana are well known tribal region from Nashik district. The tribal community from that region was partially or fully dependent on the wild green leafy vegetables to complete their nutritional need. In present study from selected tribal region of Nashik district, a total 61 traditionally used wild green leafy vegetables was identified. Among 61 species, with respect to families Amaranthaceae, Fabaceae and Asteraceae were found to be largest family of wild leafy vegetables with 22 species. Presently because of modernization in agricultural practices, negligence of uncultivated plants, less awareness, illiteracy and sudden environmental changes the naturally grown wild leafy vegetables source was limited. So present study was focused on the identification and conservation of these species for future need.

Wild food plants are commonly used in the traditional diets of indigenous people in many parts of the world, including northern Thailand. The potential contribution of wild food plants to the nutrition of the Karen and Lawa communities remains poorly understood. Wild food plants, with a focus on leafy vegetables, were ranked by the Cultural Food Significance Index (CFSI) based on semi-structured interviews. Twelve wild plant species were highly mentioned and widely consumed. The importance of the wild vegetables was mainly related to taste, availability, and multifunctionality of the species. Their contents of proximate and minerals (P, K, Na, Ca, Mg, Fe, Mn, Zn, and Cu) were analyzed using standard methods. The proximate contents were comparable to most domesticated vegetables. The contents of Mg (104 mg/100 g FW), Fe (11 mg/100 g FW), and Zn (19 mg/100 g FW) in the wild leafy vegetables were high enough to cover the daily recommended dietary allowances of adults (19–50 years), whereas a few species showed Mn contents higher than the tolerable upper intake level (>11 mg/100 g edible part). The wild leafy vegetables, therefore, are good sources of minerals and we recommend their continued usage by indigenous people. Further research on these wild leafy vegetables’ contents of antioxidants, vitamins, heavy metals, anti-nutrient factors, and food safety is recommended.

Most of the iron for our body requirements can be obtained from green leafy vegetables and nutritional anemia can be easily cured by green leafy vegetables. The iron in the ash solution was determined colorimetrically by first converting the iron into ferric form using oxidizing agent potassium persulphate and the converting the ferric into red ferric thiocynate complex [Fe (SCN)6]3- exhibiting λmax at 480 nm by treatment with potassium thiocynate reagent. The calcium is essential for strong bones and teeth while iron which along with above vegetables also present in sufficient quantity in carrot, bitter gourd, onions and tomatoes is essential constituent of hemoglobin which helps to carry oxygen to cell in various parts of the body. Calcium was determined by oxalate precipitation method, and then titrated in hot condition against 0.01 M KMnO4 solution till permanent pink colour is obtained.

This work focuses on the importance of leafy vegetables consumed in 3 localities BOLENGE, BANTOY and BOYEKA 1 and BOYEKA 2 located in the equatorial forest near the city of Mbandaka (DR Congo). The objective of this study is to identify the main spontaneous leafy vegetables gathered by the indigenous Batua people and to carry out a food and nutritional characterization. On the one hand, an ethnonutritional survey on eating habits was conducted among this indigenous Batua population, consumers of spontaneous leafy vegetables. The leafy greens that were investigated are: Ipomea batatas (L) Lam , Solanum aethiopicum L., Talinum triangulare ( jacq ) Wild, Amaranthus viridis L.; Hibiscus Sabdariffa , Manihot esculenta L. Grantz , Colocasia esculanta (L) Schot , Cecropia concolor miq , Lasimonda senegalensis schott , Erythroccoca atrovinens (Pax) Prain , Celosia trigyra L. On the one hand, a survey was conducted among 200 households with reference to some ethnonutritional data on the use and consumption of these leafy vegetables. The results reveal that these leafy vegetables are consumed in descending order by adults whose average age is over 40 years old (50.5%), followed by people whose age is between 30 and 40 years old (32%) and young people whose age is less than or equal to 30 years (17.5%). From the education point of view of the respondents, the most represented class is made up of people with no schooling (50%), followed successively by those with secondary schooling (25%), primary (23.5%) and higher (1 .5%). The socio-demographic analysis reveals that females are the majority consumers of these spontaneous vegetables (52.5%) against (47.5%) males in the 3 villages. The marital status of respondents reveals that married people are the most represented (60.5%). Slightly more than a third of people surveyed (34%) work as a lumberjack. The average percentage of consumption of leafy vegetables of these three villages ( Bolenge , Bantoy , Boyeka ) reveals that the population of Bolenge consumes more leafy vegetables (15.32%) compared to Bantoy (11.9%) and Boyeka (5.36%). Endogenous knowledge of the virtues of three most consumed leafy vegetables ( Ipomea batatas (L) Lam , Solanum aethiopicum L., Talinum triangulare ( jacq ) Wild) in the three villages, reveals that the population of Boyeka presents a higher knowledge (39.3%) than Bantoy (24.66%) and Bolenge (14%). It is observed that knowledge of the nutritional value of leafy vegetables does not correspond to the consuming population of the village, except in the Bolenge village.Mots clés : chenilles, éléments minéraux, micronutriments, insectes comestibles, oligoéléments

Leafy vegetables are common components of the human diet and are a source of antioxidant, vitamins, minerals, and bioactive compounds. Fresh-cut or minimally processed industries are always looking for product innovations. Many wild species, based on their composition, can be evaluated as potential vegetables. In this work, hedge mustard has been studied as a potential leafy vegetable, and two wild populations were grown under 100% crop water requirement (WR) and 50% WR. The effect of water reduction was monitored using non-destructive measurements of chlorophyll a fluorescence and by the analytical determination of primary or secondary metabolism associated parameters such as sugars, anthocyanins, carotenoids, phenolic compounds, and nitrate concentrations. The results demonstrated that hedge mustard [Sisymbrium officinale (L.) Scop.] can be grown with 50% WR without yield reduction. The yield was not statistically different between the two water regimes and ranged from 22.3 to 40 g plant−1 FW. Leaf nitrate concentrations showed high variability in the MI population grown with 100% WR, while in the BG population, they did not change when the WR was shifted from 100% to 50%. The total phenols were 25% higher in the leaves of plants grown under 50% WR in both wild populations. The total sugars and anthocyanins did not show significant variations. Chlorophyll a fluorescence parameters did not show significant changes. The results suggest that hedge mustard can be grown in environments with limited water availability or in the winter season using less water to avoid disease development. The highest yield was obtained from the BG population.

Humans established relations with food with their existence on earth. In various parts of the world, different types of vegetation are used as food material. Chhattisgarh, where numbers of tribes exist and used a leafy portion of various plants as a food material. The present study evaluated the total protein, total carbohydrate, and total free amino acid content in leafy vegetables used in Chhattisgarh. Total protein was estimated by Lowry method, while total carbohydrate and free amino acid content by Anthrone method and spectrophotometric method. The result showed highest protein contained in Tamarindus indica (103.98 ± 2.34 μg/mg) followed by Moringa olerifera (99.86 ± 2.32 μg/mg), Cicer arietinum (95.53 ± 2.78 μg/mg). The highest carbohydrate content was observed in the leaf of Amaranthus viridis (116.26 ± 2.33 μg/mg of plant tissue) followed by Marsilea vestita with carbohydrate content (82.35 ± 1.55 μg/mg), Chorchorus olitorius with carbohydrate content (50.46 ± 2.23 μg/mg), and highest free amino acid content was recorded in the leaves of (232.33 ± 2.05 μg/mg of plant tissue) followed by Brassica oleracea (204.94 ± 1.25 μg/mg), Cucurbita maxima (85.67 ± 2.35μg/mg). The study’s finding confirmed that wild leafy vegetables utilized by the special community of this area play a significant role in their livelihood as those vegetables contain higher nutrient level compared to conventional crops. As per the data reported, more than one million people of this region suffer from malnutrition so present study is an approach to overcome the health issue of people of this region in a sustainable manner

The present paper deals with the identification, documentation and exploration of diverse underutilized leafy vegetables consumed by the Karbi tribes of Karbi Anglong District, Assam. The NE region of India is the Gateway to India’s richest biodiversity zones important for the genetic resources’ world over. Genetic diversity of such underutilized leafy vegetables is concentrated or common in Northeast India more particularly in Karbi Anglong Hill District of Assam, which is considered to be one of the hotspots of the biodiversity in the world. The Indigenous and underutilized leafy vegetables are a source of livelihood for the local/ethnic communities of the district. In addition to food security these are also a part of culture and tradition for most of the hill tribes. These underutilized leafy vegetables are mostly found in wild forms as non-timber forest products and other natural habitats though some are domesticated and cultivated. The richness of plant diversity is largely due to ecological diversity superimposed with tribal and ethnic diversification, plant usage and religious rituals. The present paper deals with some of the common underutilized leafy vegetables used by the karbi communities. From the survey conducted in different local markets/weekly markets altogether 30 species belonging to 23 families were reported from the study area. These plant species were found to be morphologically different from each other and were found to important in the Karbi Anglong District of Assam because of their medicinal values and provide economic benefit for the rural poor people. Tabulation has been done according to their Scientific name with families, vernacular name(karbi), plant parts used, common uses, mode of propagation, ITK’s. etc. These plant species are used as vegetables which are having higher nutritional properties than commonly cultivated vegetables. Underutilized leafy vegetables and wild edible plants constitute an essential part in variation of diet and bring nutritional security and act as cheap source of healthcare component among ethnic communities. Therefore, there is a need for conducting systematic studies and research-based information on these plant species so as to establish them as economically viable crop. Domestication and bringing into cultivation is the need of the hour for promotion of these herbs beyond their confined locality. Studies on adaptability of these plant species in different environment are also important for their promotion as commercial crop.

The consumption of fruits and vegetables is of great importance in the treatment and prevention of aging, cancer and chronic-degenerative diseases caused by oxidative stress, which in turn causes the release of reactive oxygen chemical species. The demand of organic food is on the rise, and it is reflected in the significant growth of 11% in the organic food trading in the United States, the world's largest organic market. More farmers are actually producing on more certified organic land and up to now 179 countries reported activities in organic agriculture. Vegetables analyzed for this study were obtained from commercial shopping centers of the city of La Paz Baja California Sur, and were classified in four groups: tomatoes, peppers, citrus fruit and leafy vegetables; conventional, wild and organically produced. The 1,1-Diphenyl-2-picrylhydrazyl (DPPH) technique was used to measure the antioxidant activity of the plant extracts. Tomato grape organic certified with 1,273 trolox equivalent mg per gram of sample presented the highest antioxidant power. Additionally; certified organic bell pepper had the highest antioxidant power with 1,119 mg equivalent of trolox gram of sample. With regard to the group of citrus fruits, we found that the wild naranjitas had higher antioxidant power with 1.623 mg trolox equivalent per gram of sample. Finally, as far as the leafy vegetables group, wild quelite showed the highest antioxidant power with 1,313 mg trolox equivalent per gram of sample.

Wild vegetables were collected from forests, home gardens, road sides, fallow lands and farmers’ fields of Makawanpur district. Information regarding local names, seasonal availability, mode of consumption and priority for utilization were gathered by interviews with key informants, traders’ interviews and market survey of study sites. Some of nutritive values including relative importance of wild vegetables were recorded from literature. A total of 68 wild plant species belonging to 58 genera and 40 families were identified as wild vegetables. Of these, 53 species were herbs, 5 climbers, 4 species shrubs, 4 species trees, and 2 species aquatic runners. The wild vegetables were harvested mainly from March to July by women for household consumption and were also sold in the market. Amaranthus lividus, Bambusa tulda, Bauhinia purpurea, Chenopodium album, Dendrocalamus hamiltonii, Diplazium esculentum, Dryopteris cochleata, Ficus lacor, Ipomoea aquatica, Macropanax dispermus, Phytolacca acinosa, Rorripa nasturtium-aquaticum, Tectaria coduanata, were frequently used as wild vegetables. About 16 wild vegetables were sold in the market. Thus, wild vegetables not only contributed to subsistence and nutritional security of the local people, but also a source of income generation. Despite their importance, these plants have been threatened. The utilization and cultivation of these vegetables should be promoted to maintain the dietary needs of the household in Nepal. This paper attempts to highlight the use and priority of wild vegetables mainly leafy and tender shoot vegetables of Makawanpur district.

Wild edible leafy plants, thanks to their organoleptic characteristics and nutritional value that can make them be appreciated as salads by consumers, represent a good opportunity for growers and the fresh-cut industry, which are always looking for new crops to expand the number of products they offer. In this study, four wild species (dandelion, sorrel, wild chicory, and wild lettuce) were cultivated hydroponically up to the baby leaf stage in order to evaluate them as potential crops. At harvest, yield and antioxidant compounds, minerals, and nitrates content were assessed. The contribution to human mineral intake and the possible health risk associated with heavy metals were investigated. A characterization of the sensory profile was also carried out. Yield and chlorophylls and carotenoids content of the investigated species were comparable to those of common leafy vegetables. Variability in nitrate content was observed, with the lowest value in sorrel and the highest in dandelion. All species could contribute in Cr, Mg, and Se intake, and health risks due to heavy metals were excluded. Each species was well characterized by distinctive and peculiar sensory notes. In conclusion, the results of this preliminary study suggest that the four wild investigated species may be promising for baby leaf production.

This study aimed to estimate and compare the antioxidant potential as well as the levels of heavy metal contamination of Celosia argentea (Amaranthaceae), Launaea taraxacifolia (Asteracea) and Ocimum gratissimum (Lamiaceae) collected in four municipalities of South-Benin by taking into accounts the treatment prior to consumption (precooked and raw). A low extraction yield was obtained during the extraction of leafy vegetables subjected to precooking. The phytochemical screening of Launaea taraxacifolia revealed the presence of triterpenes, steroids, flavonoids and tannins. The phytochemical analysis of Ocimum gratissimum revealed the presence of triterpenes, the steroids, tannins, anthraquinones, coumarins and alkaloids. The analysis of Celosia argentea revealed the presence of triterpenes, steroids, flavonoids, tannins, anthraquinones and alkaloids. The antioxidant activity of the various extracts was found to be dose-dependent. The extracts showed significant antioxidant activities with IC50 ranging from 4.03 to 11.42 µg/ml. Ocimum gratissimum had the strongest antioxidant power followed by Celosia argentea and Launaea taraxacifolia respectively. Pre-cooking of leafy vegetables would have an effect on antioxidant activity, which resulted in a slight increase in the DPPH inhibition power of pre-cooked vegetables compared to raw one. The analysis of heavy metals showed the presence of arsenic, mercury and manganese in the different plant extracts. The highest levels were observed in leafy vegetables collect at Cotonou (Houeyiho) followed by those from Sèmè-Podji but all below the thresholds defined by the World Health Organization. The precooking promoted a decrease of the quantity in heavy metals by leaching, causing low concentration in metals of vegetables precooked in contrast with raw ones.

Crassocephalum crepioides, labeled as poor man’s food is one of the neglected and underutilized vegetables in Nigeria. The objective of this paper is therefore to validate the ethnomedicinal claim and profile the secondary metabolites of Crassocephalum crepidioides (Wild Leafy Vegetable) using in-vitro and in-silico investigations. The identification of compounds in the leaf extract with the potential to inhibit 1Z32 alpha-amylase was carried out in-silico. Liquid Chromatography Mass Spectrometry (LCMS) was employed for analysis of the ethanolic leaf extract of this plant, it revealed the presence of sinapic acid, 3-Feruloylquinic acid, dihydroquercetin, malic acid, gallic acid in the extract. Site-directed multi-ligand docking of the identified compounds was performed on 1Z32 protein of alpha-amylase molecular target using the synthetic co-crystallized ligand from the protein. The binding affinity of 3-Feruloylquinic acid (-9.4 kcal/mol) is significantly the highest when compared with sinapic acid (-8.3 kcal/mol). The interactions of this molecule with the amino acids of the protein showed that the mechanism of its inhibitory action is similar to that of the co-crystallized ligand. This study validated an earlier report that the ethanol leaf extract from C. crepidioides showed excellent antidiabetic activity, however, the antidiabetic activity could occur through its alpha-amylase inhibitory activity. Data obtained revealed that C. crepidioides could be an important wild vegetable that could require further advanced exploration rather than neglect.

Nowadays, biostimulant application is a sustainable practice with which to reduce inputs while maintaining crop yield and quality. Furthermore, the successive harvesting technique is also adopted to increase overall yield and reduce production costs in leafy vegetables. Therefore, a greenhouse experiment was performed to compare four different biostimulants, (i) two from enzymatic hydrolysate of Fabaceae species, (ii) one made from betaine, alginic acid and caidrin, (iii) and another one made from alfalfa extract, algae and molasses rich in low-molecular-weight amino acids, in order to verify their ability to limit nitrate accumulation in wild rocket leaves while boosting yield and quantitative and qualitative components through successive harvests. Successive harvests increased the marketable yield of wild rocket by 41% on average compared to the first harvest, whereas biostimulants treatments increased the yield by 38% on average compared to the control. The SPAD index was increased due to successive harvesting and biostimulant application. While biostimulant application resulted in a 24% decrease in nitrates, it also caused a considerable increase in mineral content in wild rocket leaves. Both biostimulant application and successive harvesting showed promising results, and they could be suggested in leafy vegetable cultivation due to the boosted yield and quality.

Background.Inflammation, together with related oxidative stress, is linked with the etiology of kwashiorkor, a form of severe acute malnutrition in children. A diet rich in anti-inflammatory and antioxidant phytochemicals may offer potential for the prevention and treatment of kwashiorkor. We selected and assayed five leafy green vegetables, two wild fruits, and six medicinal plants from Kenya for their antioxidant and anti-inflammatory properties. Consensus regarding medicinal plant use was established from ethnobotanical data.Methods. Antioxidant activity and phenolic content were determined using the oxygen radical absorbance capacity (ORAC) assay and Folin-Ciocalteu procedure, respectively. Anti-inflammatory activity was assessedin vitrotargeting the inflammatory mediator tumour necrosis factor-alpha (TNF-α).Results. Mangifera indica(leaves used medicinally) showed the greatest antioxidant activity (5940 ± 632 µM TE/µg) and total phenolic content (337 ± 3 mg GAE/g) butAmaranthus dubius(leafy vegetable) showed the greatest inhibition of TNF-α(IC50= 9 ± 1 μg/mL), followed byOcimum americanum(medicinal plant) (IC50= 16 ± 1 μg/mL). Informant consensus was significantly correlated with anti-inflammatory effects among active medicinal plants (r2=0.7639, P=0.0228).Conclusions. Several plant species commonly consumed by Kenyan children possess activity profiles relevant to the prevention and treatment of kwashiorkor and warrant further investigation.

Nowadays, more attention has been paid on wild plants as new source of natural antioxidants. Therefore, methanolic extracts of 10 traditionally consumed wild leafy vegetables of Bangladesh were analyzed for their total phenolic content (TPC) and free radical scavenging activity. Folin–Ciocalteu method followed by spectrophotometric measurement was used to quantify the TPC of the selected wild leafy vegetables. Free radical scavenging activity was examined utilizing 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay. Different concentrations of the plant extract were applied to ascertain the dose response relationship in inhibiting DPPH free radical. The results revealed that the TPC ranged from 102.20 to 710.42 mg GAE/100g dry weight (DW). The highest TPC was observed in Bauhinia acuminata (Shetokanchan) while Leucas aspera (Shetodhron) exhibited the lowest TPC among the undertaken vegetables. The studied samples proportionately inhibited DPPH with increasing concentrations. At high concentration (500 µg.mL-1), the percentage inhibition of DPPH radical by plant extract ranged from 68.1 ±2.65 % to 93.1 ±1.23 %. The highest DPPH radical inhibition was observed in Bauhinia acuminata (Shetokanchan) (93.10 ±1.23 %), followed by Commelina benghalensis (Bat baittashak) (91.97 ±1.31 %), Hydrocotyle sibthorpiodes L. (Sakumubakla) (91.83 ±2.13 %). The lowest DPPH radical inhibition among the studied samples was observed in Leucas aspera (Shetodhron) (68.1 ±2.65 %). IC50 values measured by DPPH assay in this study ranged from 11.64 to 313.79 µg.mL-1. The study findings indicated that the samples under study possesses strong activity against DPPH, and thus could be used as natural antioxidants in the food and/or pharmaceutical industry.

A survey was carried out to document the diversity and immune boosting claims of African indigenous leafy vegetables (AILVs) in Western Kenya. Both qualitative and quantitative methods of data collection were used. The results showed that there is diversity of AILVs in the study area with nine popular and frequently consumed, but cassava leaves, stinging nettle and russian comfry are not popular. Seven of these are cultivated but two, stinging nettle (Urtica massaica) and vine spinach (Basella alba) grow wildly. The AILVs are cultivated at subsistence level on home gardens with minimal inputs and only excess of this is sold. The religion one belonged to was significant (p<0.05) in determining consumption or not of some of the vegetables. The vegetables are rain fed and the process of harvesting is by first uprooting during thinning followed by breaking the main stem and finally plucking off the leaves with maturity. Vegetable preparation in most households was mainly by women. The elderly women were keen in this process and spent more time in preparing the vegetables which were believed to be ‘nutritious’. There was no processing and preservation of the AILVs for use during the dry season. The communities rely on wild weeds during such seasons. The AILVs though consumed for good nutrition are also associated with various medicinal and immune boosting claims. Out of the nine, five are known for various health benefits, African nightshade and spider plant for good nutrition by 31.8% and 25.1% of the respondents, respectively, slender leaf for healing power by 34%, cowpea leaves and slender leaf for anti-aging by 50% and 43.8%, respectively, and cowpea leaves (43.6%) and amaranthus (53%) for smooth skin and adding blood, respectively. Chi square analysis indicated that African night shade, spider plant and amaranthus are statistically significant (p<0.05) in contributing to good nutrition, healthy functioning of the body and immune boosting. Further analysis showed that spider plant and amaranthus are significant (p<0.05) for immune boosting.

Agricultural societies partly depend upon wild foods. Relationships between an agricultural society and its wild foods can be explored by examining how the society responds through colonization of new lands that have not been previously inhabited. The oldest clear example of this phenomenon took place about 5000 years ago in the tropical Western Pacific at the “boundary” interface between Near and Remote Oceania. An inventory of wild and domesticated food plants used by people living along “the remote side of ” that interface has been prepared from the literature. This was then assessed for the roles of plants at the time of original colonization of Remote Oceania. The majority of species are wild foods, and most of these are used as leafy vegetables and fruits. The wild food plants mostly serve as supplements to domesticated species, although there are a few that can be used as substitutes for traditional staples.

Wild Edible Plants are common in the diet of rural communities of sub-Saharan Africa. In Guinea-Bissau, West Africa, wild plant resources are widely used in human diet, but very few studies have addressed them. The aim of this study is to reveal: (1) the wild and semi-cultivated leafy vegetables consumed in Guinea-Bissau; and (2) the nutritional composition of those plants traded at the largest country market in Bissau. Our results revealed that 24 native or naturalized species with edible leaves are currently consumed by Guinea-Bissau population. Five of them were found at the market: dried leaves of Adansonia digitata, Bombax costatum and Sesamum radiatum, and fresh leaves and shoots of Amaranthus hybridus and Hibiscus sabdariffa. The analysis of the nutritional properties revealed that leaves contain a significant amount of protein (10.1–21.0 g/100 g, dry basis), high values of macronutrients and micronutrients, as well as of phenolic compounds (13.1–40.3 mg GAE/g) and a considerable antioxidant capacity (DPPH 111.5–681.9 mg Eq Trolox). Although price and availability vary among the leafy vegetables analyzed, these traditional foods appear to be a good dietary component that can contribute to food security in Guinea-Bissau and in other West African countries, as these species are widely distributed in this region.

Wild pepper plants are a valuable food source, particularly to the Sarawak local community living in rural areas. However, these plants remain unknown to the public due to the lack of scientific information disseminated to the public, and there is a rapid decline in traditional knowledge on edible plants from natural resources. The documentation and evaluation of traditional knowledge related to the diversity and usage of wild pepper plants are crucial. Therefore, this study was aimed to document and evaluate the species from Piperaceae vegetables as a food source among the Orang Ulu community in Belaga, Sarawak. Face-to-face interviews involving thirty respondents from Sungai Asap-Koyan, Belaga, Sarawak were conducted. This was to gather information on the diversity, distribution, usage, consumption and perception of wild pepper plants. From the results, wild peppers species commonly consumed were Piper umbellatum, P. borneense, P. auritifolium and P. rueckeri. Among the species, P. borneense var 1 and P. umbellatum showed significant distribution in the area. The consumption of wild pepper as leafy vegetables is common among the community as they prefer the taste, aroma, and due to their belief in its nutritional values and medicinal properties. The plant is also used as an additive in cooking, and it is widely accepted among the community. It has the potential to be commercialized and introduced as a food crop. Future studies should be conducted to assess and apply ethnic knowledge for improved performance of Piper species consumption among larger communities

The issue of nitrate contamination has become increasingly acute, with the awareness of their toxicity on the human body and the identification of increasing sources of contamination. Human intervention in the natural nitrogen cycle has serious repercussions that are manifested by its accumulation at one or more levels. The use of fertilizers in agriculture is crucial to ensure food security, but their unreasonable use causes accumulations of nitrogen in the form of nitrate ions in plants, and from here they reach human intake, over a certain amount becoming harmful. The aim of this paper is to quantify the amount of nitrates present in certain vegetables intensively consumed during spring, sources of food which if does not conform with the current recommendations of EFSA and EU, can become major factors of risk to public health. The studied material consists of 5 types of vegetables products intensively consumed in spring: lettuce (Lactuca sativa), curly lettuce (or Lollo - Lactuca sativa var Crispa), Iceberg lettuce (Lactuca sativa lime Iceberg), spinach (Spinacia oleracea) and wild garlic (Allium ursinum). The samples were collected from different commercial locations (outlets): hypermarkets (H), open markets (OM), street trade (ST) and house gate trade (HGT). The highest nitrate concentrations were found in lettuce in ST (4306 mg kg-1) and HGT (4175.5 mg kg-1), in Lollo salad in ST (4306.5 mg kg-1) and HGT (4602.75 mg kg-1) and spinach in OM (3469.25 mg kg-1). The study findings suggest that ST and HGT are commercial points that may constitute a danger to public health, the ADI value exceedingly even by 107.21% in the case of Lollo salad purchased from HGT. The issue calls for more drastic controls by the authorities.

Chhattisgarh, A state of rich biodiversity zone covered a wide range of forest having three climatic zones namely north and central eastern plateau zone, Eastern plateau zone, Western plateau zone supporting a rich biodiversity. Approximately, 30 tribal inhabitants depend on forest for survival and population live below the poverty line. The forest provide a significant role to provide them wild leafy vegetables, consumed by the tribal and other local inhabitants. These wild edible leaves not only provide the nutritional requirements of local population but ensure food security for the people living in and around forests areas. The role of present study was to enthuses the various wild edible leaves eaten by the local communities.
