Abstract:

Since ancient time, herbal drugs were highly used in the prevention and cure of various human illnesses. In India, Azadirachta indica being commonly known as Neem or Margosa is one of the multi-functional trees; belonging to Meliaceae family. In 1992, the US National Academy of Sciences was published a report entitled ‘Neem- a tree for solving global problems’. It is still considered as ‘village dispensary’ throughout the India. There are two species of Azadirachta which have been investigated; Azadirachta indica that is found in the Indian subcontinent and Azadirachta excelsa Kack that is homegrown to Indonesia and Philippines. A large number of pharmacologically active substances have been identified and isolated from the different parts of neem including azadirachtin, meliacin, gedunin, salanin, nimbin, valassin and various other components which are derived from these main compounds. Many different studies have been evaluated and authenticated for its various traditional and pharmacological activities like itching, leprosy, wound healing, spermicidal, anti-inflammatory, insecticidal, antidiabetic and analgesic etc. In the beginning of 1979, patenting on neem was started by CSIR to separate the active compounds from neem oil. Its great implantation fights with soil erosion, global warming, deforestations and desertification world-wide. In 2002, World Neem Conference raised the neem tree as an industrial or commercial plant. This review is going to explore comprehensively; traditional, pharmacological potential along with patenting, environmental & industrial significant of various parts of neem tree with safety concerns.

Abstract:

Azadirachtin is a tetranortriterpenoid derived from the neem tree Azadirachta indica A. juss. Azadirachtin has attracted worldwide attention as promising feeding deterrent, insect growth disruptor and sterilent. Azadirachtin based pesticides become very much popular because of its biodegradability and least toxicity to non- target organisms. It has now been promoted as an alternative insecticide in integrated pest management programmes. Azadirachtin has an ability to modify or suppress haemolymph ecdysteroid and juvenile hormone titres through inhibition of the secretion of brain peptides prothoracicotropic hormone and allatotropic hormone, which are responsible for inducing the synthesis and release of ecdysone from the prothoracic gland and juvenile hormone from corpora allata, respectively. Blocking the synthesis and release of ecdysone and juvenile hormone leading to disruption of coordination of moulting process. Furthermore, this compound is known to cause degenerative changes in the cells of insect endocrine glands. This review focuses on growth regulating effects of natural pesticide, azadirachtin from neem tree (Azadirachta indica A. Juss) on insects.

Abstract:

Neem plants (Azadirachta indica) are commonly found in Situbondo Regency, and currently underutilized nimba plants have many benefits, both in agriculture as pesticides and in pharmaceuticals as medicines. The content of the active compound is more commonly found in nimba seeds. The largest active compound that is an insecticide in neem seeds (Azadirachta indica) is azadirachtin. Azadirachtin is a group of terpenoid compounds which are generally non-polar so that the extraction process can use non-polar solvents. In this study using oil as a carrier solvent, it is known that oil is non-polar. This research was conducted with the aim to know the organoleptic test results of neem seed powder (Azadirachta indica) in oil variations. Organoleptic test results showed physical changes of the three oils, clearly visible in the color produced after treatment. The results of the three samples showed that the color was not clear (turbid). The aroma produced from each oil is not rancid and the pH measurement shows an increase from 5 to 6.

Abstract:

The neem tree has long been recognized for its unique properties both against insects and in improving human health. It is grown in most tropical and sub-tropical areas of the world for shade, reforestation and for the production of row material for natural insecticides and medicines. Azadirachtin, a complex tetranortriterpenoid limonoid from the neem seeds, is the main component responsible for the toxic effects in insects. Six international conferences on neem and a vast scientific literature report both the antifeedant and physiological effects of neem. This article reviews the behavioral and physiological properties of azadirachtin, including effects on insect reproduction, direct and "secondary" antifeedancy, and the physiological effects measured as growth reduction, increased mortality and abnormal and delayed moults. These effects are here categorized in two ways: direct effects on cells and tissues and indirect effects exerted via the endocrine system. It also describes the work carried out to date to identify the mode of action of azadirachtin at the cellular level. The differential effects between animal phyla and over non-target organisms are discussed and point to its potential success as a safe insecticide.

Abstract:

Neem (Azadirachta indica A. Juss) is a member of Meliaceae family, a fast-growing tropical evergreen plant whose products were found effective against economically important insect pests and diseases. All parts of this plant particularly leaf, bark, and root extracts have the biopesticidal activities. Azadirachtin, a biopesticide obtained from neem extract, can be used for con-trolling various insect pests in agriculture. It acts on insects by repelling them, by inhibiting feeding, and by disrupting their growth, and reproduction. Neem-based formulations do not usually kill insects directly, but they can alter their behavior in significant ways to reduce pest damage to crops and reduce their reproductive potential. The neem is considered as an eas-ily accessible, eco-friendly, biodegradable, cheap, and non-toxic biopesticide which control the target pests. Thus, this re-view highlighted the extract, byproducts and roles of neem that can be used as potential biopesticide in agriculture.

Abstract:

The versatility of the neem tree Azadirachta indica A. Juss. is reviewed. This species, native to India, grows in nutrient-poor soils in arid habitats and has tremendous potential for human use. Various derivatives of the tree have potential use in toiletries, pharmaceuticals, the manufacture of agricultural implements and furniture, cattle and poultry feeds, nitrification of soils for various agricultural crops, and pest control. Since neem is a natural renewal resource producing extensive useful biomass, its propagation and economic exploitation will be beneficial, particularly to the Third World. In recent years, some useful commercial products have been developed from A. indica, and mere is considerable scope for future product development. Potentially profitable lines of research on this plant species are suggested.

Abstract:

AbstractLeaves of the neem tree, Azadirachta indica A. Juss. (Meliaceae), have been used for centuries in India to protect stored grain from insect attack. Recent concern for the effects of synthetic insecticides on the environment and human health has provided the impetus for a reappraisal of the utility of neem derivatives as botanical crop protectants. Neem and its active principle, the limonoid azadirachtin, have several properties that are highly desirable for a natural insecticide. Azadirachtin is the most potent natural insect antifeedant discovered to date, suppressing insect feeding at concentrations of less than 1 part per million. Azadirachtin is also a potent insect growth regulator, which acts by disrupting molting and development, and interfering with reproduction in adult insects. These actions have been observed in over 90% of the more than 200 species of pest insects tested to date. Neem also has systemic action in some plants which could prove extremely valuable against stem- and root-feeding pests that are difficult to control. Finally, neem is essentially non-toxic to vertebrates, and in fact has a long history of medicinal use in southeast Asia.In the present paper we review our research aimed at developing a neem-based insecticide for use against pests of Canadian agriculture. We document the potent antifeedant action of azadirachtin in laboratory bioassays against the European corn borer, Ostrinia nubilalis Hübner, and the variegated cutworm, Peridroma saucia Hübner, and the molt-disrupting action of the compound in the migratory grasshopper, Melanoplus sanguinipes Fab., and the large milkweed bug, Oncopeltus fasciatus Dallas. Both antifeedant and insect growth regulatory activities of various samples of neem seed oil are shown to be correlated to azadirachtin concentrations in the oils. Field trials of an experimental neem insecticide conducted against pests of crucifers, corn, and potato in British Columbia, Ontario, and Prince Edward Island, respectively, indicate that the neem insecticide provides pest control as effective as or better than pyrethrum, the current botanical insecticide of choice for organic growers. The commercial prospectus for neem insecticides in Canada is discussed in light of our results.

Abstract:

The Neem tree is of ornamental, revegetation, biomass and medicinal value. The compound azadirachtin, which is derived from Neem seeds, is commercially used for insecticidal properties. In a 2×2 factorial experiment, Neem seedlings were either colonized with the mycorrhizal fungi Glomus intraradices or noninoculated and fertilized with full strength Long Ashton Mineral Solution at 11 or 22 ppm P. Mycorrhizal and P main effects were highly significant (p-value<0.001) with all growth parameters except R:S ratio. Mycorrhizal plants had greater leaf number, leaf area, leaf dry weight, shoot and root dry weight than noncolonized seedlings. The higher P (22 ppm) level plants had superior growth compared with low P plants. Leaf area and leaf dry weight were similar in mycorrhizal/low P plants and nonmycorrhizal/high P plants. These results suggest that mycorrhizal growth enhancement has important implications for Neem trees which are found in agriculturally poor soils in hot and arid regions.

Abstract:

Neem, has thrown the light worldwide in recent years, due to its wide range of medicinal properties. The tree has been largely used in Naturopathy, Unani and Homoeopathic medicine and has become a lodestar of current medicine. Further it elaborates a vast array of biologically active compounds that are chemically diverse and structurally complex. More than 150 compounds have been isolated from different parts of neem and these have been divided into two major classes isoprenoids and non-isoprenoids, which are proteins and carbohydrates. Further, it consists of sulphurous compounds, polyphenolic compounds such as flavonoids and their glycosides, dihydrochalcone, coumarin, tannins and aliphatic compounds. All parts of the neem tree viz., leaves, flowers, seeds, fruits, roots and bark have been used traditionally for the treatment of inflammation, infections, fever, skin diseases, dental disorders, etc. Every part of the neem tree viz., roots, seeds, flowers, bark, leaves, fruit pulp and its constituents have been demonstrated to exhibit immune modulatory, anti-inflammatory, anti hyperglycaemic, antiulcer, antimalarial, antifungal, antibacterial, antiviral, antioxidant, antimutagenic, antidiabetic and anticarcinogenic properties.

Abstract:

The antifeedant activity of Neemix 4.5 EC, a commercial formulation of azadirachtin from the neem tree (Azadirachta indica A. Juss), was tested against adult Nezara viridula (L.) in the laboratory using a cowpea pod-dip method. A toxicity assay was conducted by dipping fourth-instar nymphs. Feeding by adults was significantly reduced in treated pods compared with controls, based on counts of salivary deposits on pod surfaces, inside pod walls and on seeds. The antifeedant effect of azadirachtin was significantly greater on pods treated with 5% aqueous solution than on those treated with 0.5%, indicating that the antifeedant activity was related to concentration. Bugs were initially repelled by Neemix before approaching treated pods to feed. The LC50 for nymphs was 61% (27450 ppm azadirachtin) at 2 d and ranged from 1.8 to 6.2% (810 to 2790 ppm) at 5 d post-treatment, which indicated that neem was slow acting. Sublethal treatment of nymphs disrupted molting and caused morphological defects in adults. Development time to adulthood also was prolonged, and longevity of females was reduced by neem treatments. Azadirachtin may provide an effective component of a comprehensive management program for N. viridula.

Abstract:

O problema da resistência em nematódeos gastrintestinais de caprinos, associado ao crescente interesse por alternativas de controle, levou à investigação da ação de Azadirachta indica sobre estes parasitas. No teste in vitro observou-se a ação ovicida e larvicida de extratos aquosos de folhas verdes e secas de Neem, em cinco concentrações. No teste in vivo administrou-se 30g de folhas secas por animal/dia, durante cinco dias. Os animais foram monitorados através de OPG diário durante 28 dias e as larvas foram quantificadas e identificadas através de coprocultura. Detectou-se a predominância de Haemonchus sp. na estação chuvosa e de Trichostrongylus spp. na estação seca. O extrato aquoso de folhas secas in vitro, na concentração de 240.000ppm, reduziu em 89% a eclosão das larvas de nematódeos gastrintestinais. Entretanto, esta concentração é muita elevada e inviabiliza sua aplicação no controle da verminose. A administração oral de folhas secas trituradas não reduziu o OPG dos animais durante um período de 28 dias após o tratamento. Estudos investigativos com A. indica devem se concentrar na ação biológica do óleo extraído diretamente da semente, que possui maior quantidade de azadirachtina que as folhas. A administração do óleo também é mais fácil, já que as folhas têm sabor amargo e são evitadas pelos animais.

Abstract:

In the agricultural trade, nitrogen fertilizer is one among the popular fertilizers within the world market. However, the high use of nitrogen fertilizers causes negative impacts within the type of environmental pollution, each in water, soil, and within the air. Nitrification inhibitor required to enhance the potency of nitrogen fertilizer use to realize additional economical production of food crops and minimize fertilizer related pollution of the environment. Neem (Azadirachta indica) act as an inhibitor nitrification that contained high tannin and the other secondary metabolite compounds. Neem plants encapsulated by urea as a nitrification inhibitor can increase nitrogen efficiency in the soil during fertilization. This research is a computational experiment research in solving problems using Molecular Docking Analysis. Molecular Docking method was performed using AutoDock Vina Tools 1.5.6 and Open Babel 2.4.1 Program. The use of molecular docking aims to predict ligand bonds and target proteins that focus on affinity and bond interactions. The high and low affinity of ligand-protein bonds is influenced by free bond energies, surface interactions, and intermolecular interactions. The results represent Neem (A. Indica) contains high tannin and the other secondary metabolite compounds (Nimbin, Nimbidin, Nimbic Acid, Nimbidinin, Nimbinin, Azadirachtin, Diepoxy Azadiradione, Dyhidrogedunin, Gallic Acid and Gedunin). Those metabolite compounds can inhibiting 4 enzymes such as methane monooxygenase, Hydroxylamine oxidoreductase, Nitric oxide reductase and Nitrite Reductase. From 10 metabolite compounds, Diepoxy Azadiradione and Gedunin may become the most stable complex that indicated become strength binding energy based on the lowest energy score of −10.3 kcal/mol. HIGHLIGHTS One of the agricultural problem is the inefficiency of Nitrogen fertilization will be released in the form of N2O and Nitrate gases which pollute the environment as a result of the nitrification process Azadirachta indica is known to have secondary metabolite which have the ability to inhibit nitrification The molecular docking method was used as an initial analysis of the effectiveness of secondary metabolites from Azadirachta indica inhibiting enzymes that play a role in the nitrification process GRAPHICAL ABSTRACT
