Abstract:
North American ginseng (Panax quinquefolius L.) is a valuable and widely used medicinal plant and Ontario has become the largest grower of ginseng in North America. Ginseng has been grown in Ontario for over 50 years and has reached the land race stage. The phytochemistry of Ontario ginseng land races was characterized using high performance liquid chromatography (HPLC) coupled with a diode array detector (DAD), evaporative light scattering detector (ELSD), or mass spectrometry (MS) to assess ginsenoside and monosaccharide content. Nuclear magnetic resonance (NMR) was used successfully as a metabolomic tool to distinguish Ontario ginseng land races and ginseng species. Ginsenoside variation was high within and among Ontario ginseng land races and variation in ginsenoside content was correlated positively to the level of inhibition of the drug metabolizing cytochrome P450 enzyme, CYP3A4. Along with the assessment of ginsenosides, LC/MS/MS and LC/ELSD methods were developed to characterize malonyl ginsenosides and monosaccharide components respectively in Ontario ginseng. Malonyl ginsenosides accounted for a significant percentage of total ginsenoside content and glucose was found to be the major monosaccharide component. Although chromatographic ginsenoside analysis did not differentiate land races, 1H NMR was successfully applied to distinguish ginseng species and two of five land races. The results from this study contribute to the validation and characterization of Ontario ginseng and add to the value of this important medicinal crop.

Abstract:
Two species of mountain ash (Sorbus decora and S. americana) distributed in Eeyou Istchee (James Bay, Quebec) were assessed for differences in their DNA, gene expression and antioxidant capacity to determine if environment or genetic variation contributed to previously observed differences in medicinal, and possibly antidiabetic, activity. Samples of both species were taken from 20 populations throughout Eeyou Istchee. Quantitative real time PCR analysis showed species and tissue specific expression for two likely antidiabetic genes. Significantly higher expression was observed in samples from coastal communities, along with increasing expression with latitude. Similar patterns were observed when antioxidant capacity of bark samples were tested using ORAC and DPPH assays. Analysis of genetic differences using nuclear microsatellites did not show significant structuring among populations. These results suggest that it is not genetic dissimilarities which led to these differences, but likely plants responding to immediate stresses in their environment.
Deux espèces de sorbiers (Sorbus decora et S. americana) sont réparties dans Eeyou Istchee (Baie James: Québec). Elles ont été évaluées pour leurs similarités dans leur ADN, leur expression génique et leurs propriétés antioxydantes afin de déterminer si l'environnement ou la génétique contribue aux différences déjà observées dans l'activité médicinale des sorbiers. Des échantillons de vingt populations ont été récoltés à travers Eeyou Istchee. Les analyses de PCR en temps réel ont démontré que l'expression de deux gènes liés à des métabolites secondaires était spécifique aux espèces et aux tissus. Une expression plus élevée a été observée dans les échantillons en provenance des communautés côtières et avec la latitude. L'analyse de la capacité antioxydante a démontré des patrons similaires. L'analyse des différences génétiques à l'aide de microsatellites n'a pas révélé de groupes bien délimités. Ces résultats suggèrent que ces différences sont liées à la réponse des plantes au stress immédiat provenant de leur environnement.

Abstract:
Sciadopitys verticillata was subjected to three propagation treatments designed to inhibit coagulation of its latex-like sap at the cut ends of the stem cuttings. Twenty-four hour soaking in water prior to rooting hormone application significantly enhanced production of adventitious roots. Old wood stem cuttings from shade-grown trees rooted at higher proportions than stem cuttings collected from sun-grown trees. Height, age, and place of origin of the source trees were not important factors in successful rooting. Antibacterial activity against some human pathogens and soil bacterial species was detected in latex application trials but the antibiotic activity was not related to the bacterial Gram reaction. The latex-like sap inhibited none of four plant pathogens tested. A suspension of the water insoluble latex-like sap of S. verticillata had a pH of 5.8. Antibacterial activity of S. verticillata sap was heat stable, which indicates the activity was not protein-based.

Allelopathy is an ecological phenomenon defined as the chemical, positive or negative interference of compounds produced by plants on growth and development of other plants. This phenomenon can modify the structure of plant communities, significantly influencing processes such as ecological succession and species dominance. However, the production of compounds is often affected by environmental conditions, and the allelopathic response of the same species can be differentiated depending on the habitat that is. Thus, the objective of this study was to assess whether different forest types within the State of Paraná can influence the allelopathic effect of native plant species recommended for restoration. The plant species were collected from two forest types: semideciduous forest and Tropical Rainforest. Representing the group of pioneer species were collected J. micrantha, C. and M. pachystachya bimucronata; The group was composed of secondary species by species S. terebinthifolius and C. fissilis; climax species was chosen as the E. edulis. The chemical composition of the collected individuals and allelopathy on germination and early development of pioneer species in secondary and climax species, and secondary, in the climax species, simulating the ecological succession that occurs in the field was analyzed. Species showed differences in the concentration of allelopathic compounds, but the species S. terebinthifolius was the only one to present qualitative difference between chemical compounds. It was found that these species may show differences in potential allelopathic effect and, depending on the forest type in which they were collected, mainly as to speed germination and seedling height field. Finally, the collected species in semideciduous forest were more chemically aggressive than the same species collected in Dense Forest, within the State of Paraná
A alelopatia é um fenômeno ecológico definido como a interferência química, positiva ou negativa, de compostos produzidos pelas plantas sobre o crescimento e desenvolvimento de outras plantas. Este fenômeno pode modificar a estrutura de comunidades vegetais, influenciando significativamente processos como sucessão ecológica e dominância de espécies. Porém, a produção dos compostos é frequentemente afetada por condições ambientais, e a resposta alelopática de uma mesma espécie pode ser diferenciada dependendo da habitat que se encontra. Desta forma, o objetivo deste trabalho foi avaliar se diferentes formações florestais dentro do Estado do Paraná podem influenciar o efeito alelopático de espécies nativas recomendadas para restauração vegetal. As espécies vegetais foram coletadas em duas formações florestais: Floresta Estacional Semidecidual e Floresta Ombrófila Densa. Representando o grupo das espécies pioneiras foram coletadas J. micrantha, C. pachystachya e M. bimucronata; o grupo de espécies secundárias foi composto pelas espécies S. terebinthifolius e C. fissilis; como espécie clímax foi escolhido o E. edulis. Foi analisada a composição química dos indivíduos coletados e a alelopatia na germinação e desenvolvimento inicial das espécies pioneiras sob as espécies secundárias e clímax, e das secundárias, sob a espécie clímax, simulando a sucessão ecológica que ocorre em campo. As espécies apresentaram diferença na concentração dos compostos alelopáticos, mas foi a espécie S. terebinthifolius a única a apresentar diferença qualitativa entre os compostos químicos. Constatou-se que as espécies estudadas podem apresentar diferença no potencial e efeito alelopático, dependendo da formação florestal em que foram coletadas, principalmente quanto à velocidade na germinação e altura das mudas em campo. Por fim, as espécies coletadas na Floresta Estacional Semidecidual foram mais quimicamente agressivas do que as mesmas espécies coletadas na Floresta Ombrófila Densa, dentro do Estado do Paraná.

Mimosa tenuiflora (Willd.) Poiret (jurema preta) is a species in the Fabaceae family, native to the Caatinga, found throughout the Brazilian Northeast. In folk medicine, the shells of the stem and root of jurema preta are used in treatment of several diseases, as burns and inflammations, besides being maid traditionally as drink in indigenous rituals. Regarding to the root bark, there are few studies described in the literature about its phytochemical profile and biological properties. In this way, the present study has proposed perform a phytochemical study of the extracts from the root bark of Mimosa tenuiflora. For this, it was performed the fractionation of chloroformic extract from the column chromatography (CC), and the structural determinations of the isolated compounds were carried out by technique of nuclear magnetic resonance (NMR) of 1H and 13C, besides the identification and quantification of phenolic substances in the chloroformic extracts and the ethyl acetate from the high-efficiency liquid chromatography with diode arrangement detector (HPLC-DAD) and consequent validation of applied analytical method. Were also carried out assessment of anticholinesterasic activity of the extracts by the method of Ellman and quantification of the total flavonoid content of the crude extract through spectrophotometric method using as reactant aluminum chloride (AlCl3) and standard curve with quercetin. As a result, were obtained from the chloroformic extract a mixture of the ?-sitosterol and stigmasterol steroids and the betulinic acid triterpene. From of the HPLC-DAD were identified polyphenols such as catechin, epicatechin and procyanidin B2 beyond the gallic acid in the ethyl acetate extract and procyanidin B2, in the chloroformic extract of this species. With the validation of the analytical method, this proved to be reliable and suitable for the quantification of the substance catechin and epicatechin in the ethyl acetate extract, according to criteria recommended by the National Health Surveillance Agency ? NHSA. Regarding the anticholinesterasic activity, among the tested extracts of black jurema, the gross and the ethyl acetate were the ones who showed greater inhibition capacity on the enzyme acetylcholinesterase (AChE) in relation to other, presenting percentages of 89% + 0,31 and 93,8% + 0,4, respectively, what classifies this species as a potent inhibitor. The total flavonoids content quantified in the crude extract of Mimosa tenuiflora was of 1,386g/100g extract. Thus, this work indicates that the species Mimosa tenuiflora is a promising source of bioactive substances of chemical-medicinal interest, besides being a strong natural candidate that can aid in the treatment of Alzheimer's disease. It is important to mention that the present study provides an unprecedented contribution about the chemical composition of root bark of black jurema, since to date no records were found in the literature on phenolic constituents of this part of the plant.

The purpose of this work is to carry out the phytochemical study and evaluate biological activities of the essential oil and extracts of the Pimenta pseudocaryophyllus (Gomes) L.R. Landrum (Myrtaceae) leaves. Chapter 1 provides a review of the main botanical aspects of the genus Pimenta, its chemical composition and pharmacological potential. Chapter 2 describes the occurrence of infraspecific variability in P. pseudocaryophyllus. For this the essential oils from 12 specimens of P. pseudocaryophyllus that occur naturally in three different locations of the Brazilian Cerrado underwent a qualitative and quantitative analysis by gas chromatography-mass spectrometry (GC/MS). The multivariate statistical analysis identified three chemotypes of P. pseudocaryophyllus, characterized by the predominance of citral, (E)-caryophyllene and (E)-methyl isoeugenol constituents. Chapter 3 presents the phytochemical assessment of the hexane, dichloromethane, ethyl acetate and aqueous fractions obtained from the crude ethanol extract of P. pseudocaryophyllus leaves. Chromatographic and spectrophotometric (1H and 13C) methods enabled the isolation and identification of lupeol, α-and 􀈕-amyrin, oleanolic, ursolic and betulinic acids, quercetin, quercitrin, isoquercitrin, afzelin, avicularin, guaijaverin, catechin, ellagic acid and gallic acid. Chapter 4 assesses the antimicrobial activity of the ethanol extracts, fractions (hexane, dichloromethane, ethyl acetate and aqueous), essential oils and isolated compounds of citral (CQ) and (E)-methyl isoeugenol (MQ) chemotypes of P. pseudocaryophyllus. The broth microdilution test was applied to determine the minimum inhibitory concentration (MIC) against strains of Gram(+) and Gram(-) bacteria, and of Candida and Cryptococcus spp fungi. The CQ and MQ dichloromethane fraction, CQ ethyl acetate fraction, and CQ essential oil were the most active (MIC = 62.5 to 500 mg / mL) against Gram(+). The oleanolic acid proved to also be responsible for this action. The CQ and MQ extracts of P. pseudocaryophyllus were active (MIC = 7.8 to 500 mg / mL) against most strains of Candida spp and Cryptococcus spp, where gallic acid, ellagic acid and quercitrin contributed to this action. The data obtained indicate the antimicrobial potential of CQ and MQ P. pseudocaryophyllus against some infectious diseases. Chapter 5 describes the antinociceptive activity, in mice, of CQ and MQ ethanol extracts, CQ fractions and CQ essential oil, and the anti-inflammatory activity of CQ crude ethanol extract of P. pseudocaryophyllus. The abdominal writhing test induced by intraperitoneal administration (ip) of acetic acid (1.2% v / v) and the ear edema test induced by croton oil (2.5% V/V) were performed. The CQ crude ethanol extract (2000, 1000 and 500 mg/kg, po) showed a dose-dependent antinociceptive effect. Among the fractions, only the aqueous fraction was not active. The CQ essential oil (60, 200 and 600 mg / kg, po) presented significant antinociceptive activity, probably because of its high citral concentration. Pretreatment with CQ crude ethanol extract (2000, 1000 and 500 mg / kg) reduced edema by 14.3 ± 0.4 mg (control) to 10.9 ± 0.5, 11.3 ± 0, 4, 10.5 ± 0.5 mg, respectively. The analgesic effect may be related to an anti-inflammatory action observed in the ear edema test.
O presente trabalho teve como objetivos realizar o estudo fitoquímico e avaliar atividades biológicas do óleo essencial e de extratos da folha de Pimenta pseudocaryophyllus (Gomes) L. R. Landrum (Myrtaceae). O Capítulo 1 traz uma revisão bibliográfica do gênero Pimenta onde são abordados os principais aspectos botânicos, a composição química e o potencial farmacológico. O Capítulo 2 descreve a ocorrência de variabilidade infraespecífica em P. pseudocaryophyllus. Para tanto, foi realizada a análise qualitativa e quantitativa, por cromatografia gasosa acoplada a espectrometria de massas (CG/EM), do óleo essencial das folhas de 12 espécimes de P. pseudocaryophyllus que ocorrem naturalmente em três diferentes localidades do Cerrado brasileiro. A análise estatística multivariada dos dados identificou três quimiotipos de P. pseudocaryophyllus, caracterizados pela predominância dos constituintes citral, (E)-cariofileno e (E)-metilisoeugenol. O Capítulo 3 apresenta os resultados da avaliação fitoquímica das frações hexano, diclorometano, acetato de etila e aquosa obtidas a partir do extrato etanólico bruto das folhas de P. pseudocaryophyllus. A partir da utilização de técnicas cromatográficas e espectrofotométricas (RMN 1H e 13C) foi possível isolar e identificar os triterpenos pentacíclicos lupeol, α- e 􀈕-amirina, os ácidos oleanólico, ursólico e betulínico, os flavonóides quercetina, quercitrina, isoquercitrina, afzelina, avicularina, guaijaverina e catequina, e os ácidos gálico e elágico. O Capítulo 4 expõe a avaliação da atividade antimicrobiana dos extratos etanólicos brutos, frações (hexano, diclorometano, acetato de etila e aquosa), óleos essenciais e substâncias semipurificadas de P. pseudocaryophyllus quimiotipos citral (QC) e (E)- metilisoeugenol (QM). Foi utilizado o teste da microdiluição em caldo, que permitiu determinar a Concentração Inibitória Mínima (CIM) frente a cepas de bactérias Gram(+), Gram(-) e fungos Candida spp. e Cryptococcus spp. As frações diclorometano (QC e QM), acetato de etila (QC) e o óleo essencial do quimiotipo citral foram os mais ativos (CIM = 62,5-500 μg/mL) frente as bactérias Gram(+), o ácido oleanólico mostrou ser um dos responsáveis por essa ação. O QC e QM foram ativos (CIM = 7,8 – 500 μg/mL) frente à maioria das cepas fúngicas, sendo que ácido gálico, ácido elágico e quercitrina contribuíram para essa ação. Os dados obtidos indicaram que P. pseudocaryophyllus QC e QM apresentam potencial antimicrobiano. O Capítulo 5 descreve a avaliação da atividade antinociceptiva, em camundongos, dos extratos etanólicos brutos (QC e QM), frações e óleo essencial (QC) de P. pseudocaryophyllus e a atividade anti-inflamatória do extrato etanólico bruto (QC) de P. pseudocaryophyllus. Foram utilizados os testes das contorções abdominais induzidas pela administração intra-peritonial (i.p.) de ácido acético (1,2%, v/v) e do edema de orelha induzido pelo óleo de cróton (2,5%, V/V) em camundongos. O extrato etanólico bruto QC (2000, 1000 e 500 mg/kg, v.o.) demonstrou efeito antinociceptivo dose-dependente. Dentre as frações, apenas a aquosa não foi ativa. O óleo essencial QC (60, 200 e 600 mg/kg, v.o.) demonstrou significativa atividade antinociceptiva, provavelmente por causa do seu elevado teor em citral. O pré-tratamento com o extrato etanólico bruto QC nas dose 2000, 1000 e 500 mg/kg reduziu o edema de 14,3±0,4 mg (controle) para 10,9±0,5; 11,3±0,4; 10,5±0,5 mg, respectivamente. A ação analgésica pode estar relacionada a uma ação anti-inflamatória, observada no teste de edema de orelha.

Abstract:
The ranking of seeds represents remarkable transition phase for photosynthasis and sexual reproduction, this phase is complex & successful method for sexual reproduction in vascular plants. As we know that seed containe the genetic repository of past & potential for its perpetuation in the future. The dormancy in seeds induced by desciccation & the hormone abscisic acid (ABA) till the condition in growth become favorable. The well developed seeds eliminates requirement of water during sexual reproduction & allows fertilization events to occur over long distances. Germination of seeds in particular situation and season is determines the interaction between dormancy and relating factors like phytochemical development to give healthy bioactives, which strongly influence on the termination of dormancy or initiatin of germination and seedling in many plant species like photo-hormons, light, temperature, water, neutrients and mechanical cuse. Seeds of particular plants needs difreent pretreatment to give vigor seedlings even in production so far. The entiteled chapter represents amulgumation of agriculturists and life scientists. Recent significant progress has been endorsed in seed physiology to solve the practical issues constantly associated with the seeds. The aim & objective of this articale is to enlighten the reader, not only about the different aspects of the seed physiology it also includes the development of bioactive (secondary metabolites) in the healthy seeds. This resorce of pice will help researcher to sencitize about the type of healthy bioactive available in the shalls of seedlings. This could be the reason to isolate the biomolecules from a well evaluate seeds, seed evalution not only the sorce to get healthy crops in agricultural scince it also helps so for a phytochemist to get theuraputicaly active biomolecules, without destroying the nature, which could be the value added thought to combat with the burning issues associated with the existing situation (COVID Omicron, viral infection and all kinds of disorder associated with the immune system). Henceforth, endorsed personage to give real-time attention to plant propagation, particularly for indigenous tree species and seedling multiplication should be regarded as a primary need to make not only a sustainable environment but also become a treasure to fulfill the needs of industry application in the field of agriculture plus R & D.
