Studies on the Seed Fat Composition of Moringaceae family
The component fatty acids of the seed fats of Moringa pterygosperma and Moringa concanensis have been investigated by using the techniques of urea-adduct segregation and quantitative paper
Natural product drug discovery and development: new perspectives on international collaboration.
A discussion of policies for international collaboration and compensation being implemented by several developed country organizations, and the perspectives on the current developments given by representatives of some of the source countries located in the regions of greatest biodiversity.
Bioefficacy of neem products and insecticides against the incidence of whitefly, yellow mosaic virus and pod borer in Black gram
Efficacy of some indigenous neem products, insecticides and their admixtures were tested and it was indicated that admixture treatments not only reduced the incidence of whitefly and yellow mosaic but also of pod borer.
Efficacy of Neem in combination with cow urine against mustard aphid and its effect on coccinellid predators
The results conclude that the incidence of mustard aphid can be safely and successfully managed by adopting 3 or 4 foliar sprays of neem kernel extract (in cow urine) 3% either alone or in combination with reduced dose of Dimethoate 0.03%.
Calcium pump activity of sarcoplasmic reticulum in diabetic rat skeletal muscle.
The results suggest that diabetes is associated with enhanced sarcoplasmic reticular Ca2+ pump activity, and this may account for the hyperfunction of skeletal muscle in this disease.
Sipandinolide: a butenolide including a novel type of carbon skeleton from Siparuna andina.
From a lipophilic extract of leaves of Siparuna andina (Monimiaceae), two new compounds have been isolated: sipandinolide, a compound with a novel type of carbon skeleton and (-)-cis-3-acetoxy-4',5,7-trihydroxyflavanone, which showed moderate antiplasmodial activity.
In vitro antiplasmodial activity of Central American medicinal plants
In vitro antiplasmodial activities of 14 plant species traditionally used in Central America for the treatment of malaria or fever were evaluated, and bioactivity‐guided fractionation of Piper hispidum yielded 2′,4,6′‐trihydroxy‐4′‐methoxydihydrochalcone (asebogenin) as an active compound.
