Acetylcholinesterase (AChE) inhibitors are widely used in Alzheimer’s treatment, but they also crucial for their action on organophosphorus insecticides. The latter exert toxicity by inhibiting the AChE enzyme insects, leading to death. Amaryllidaceae alkaloids have been proven be potent inhibitors. In present study methanolic extracts and essential oils being obtained from species of Asteracea...

Introduction: ashwagandha (Withania somnifera) is an important medicinal plant in Indian traditional system of medicine and traditionally has been used for several medicinal purposes in India. the present study was conducted to evaluate the anti-inflammatory effect of hydroalcoholic extract of ashwagandha against denaturation of protein in vitro. Methods: The test extract at different concentra...

Gambir (Uncaria gambir) is a herbaceous plant that has alkaloid level sin the form of chemicall compounds suchas catechins, tannin catecu (tannin/tannat), querchitin, flouresin, and several other compounds. The aim this study to deterine effectiveness concentration gambir leaf extract (U. Roxb), against mortality fire caterpillarpest (S.asigna). Research was arrenged in anonfactorial Randomized...

Ergot alkaloids produced by a fungal endophyte (Epichloë coenophiala; formerly Neotyphodium coenophialum) that infects tall fescue (Lolium arundinaceum) can induce persistent constriction of the vasculature in ruminants, hindering their capability to thermo-regulate core body temperature. There is evidence that isoflavones produced by legumes can relax the vasculature, which suggests that they ...

The fingerprint profiles of methanol extract and ethyl acetate sub fraction of Azadirachta indica leaves were conducted using preliminary phytochemical screening and high performance thin layer chromatography (HPTLC) analysis. Preliminary phytochemical screening was performed using various biochemical tests. Alkaloid, flavonoid, tannin, saponin and phenol were present in both the extract/subfra...

background & aim:combretaceae family is   known for efficacy in the management of sickle cell disorder (scd). based on   the earlier reports of anti-sickling property of terminalia genus the study investigates in vitro antisickling properties of terminalia arjuna and terminalia   bellirica. experimental: anti-sickling   assay of methanolic and aqueous extract of t. arjuna and t. bellirica   on ...

A strategy has been established for preparative-layer chromatography of the alkaloid fraction extracted from the plant Fumaria officinalis. The extract, obtained by maceration and percolation of ground plant material with 0.5 mol L aqueous acetic acid, was re-dissolved in methanol and fractionated on alumina by column chromatography. Two fractions, containing medium and high-polarity alkaloids,...

A new indole alkaloid named bufobutarginine (1), along with three known bufotenines, namely, serotonin (2), bufotenidine (3), and bufotenine (4), were isolated from the water extract of toad venom. Their structures were elucidated by spectral methods. This is the first time that arginine has been found to be involved in the biosynthesis of bufotenines in parotid of toad. The cytotoxic activitie...

Synergism and antagonism impact of different plant metabolites present in crude fruit extract of Tribulus terrestris 'the herbal Viagra' have been studied. Variability in plant composition, biomass and metabolites concentration in different modules was significantly contributed by spatial factor. However the edhaphic parameters also changes with both spatial and temporal factors significantly. ...
