It is becoming increasingly evident that the formation of arbuscular mycorrhiza (AM) enhances secondary metabolite production in shoots. Despite mounting evidence, relatively little is known about the underlying mechanisms. This study suggests that increase in artemisinin concentration in Artemisia annua colonized by Rhizophagus intraradices is due to(More)
OBJECTIVE To investigate the medicative effects of medium-polar (benzene:acetone, 1:1, v/v) extract of leaves from Stevia rebaudiana (family Asteraceae) on alloxan-induced diabetic rats. MATERIALS AND METHODS Diabetes was induced in adult albino Wistar rats by intraperitoneal (i.p.) injection of alloxan (180 mg/kg). Medium-polar extract was administered(More)
Sodium valproate is a widely prescribed broad-spectrum antiepileptic drug. It shows high inter-individual variability in pharmacokinetics and pharmacodynamics and has a narrow therapeutic range. We evaluated the effects of polymorphic uridine diphosphate glucuronosyltransferase (UGT)1A6 (541A>G, 552A>C) metabolizing enzyme on the pharmacokinetics of sodium(More)
OBJECTIVES To evaluate the antifertility properties of extracts of leaves of Plumbago zeylanica Linn. (Plumbaginaceae). METHODS The effects of petroleum ether, chloroform, acetone, ethanol and aqueous extracts of the leaves of P. zeylanica on the estrous cycle of rats were studied at two dose levels, namely, 200 and 400 mg/kg. The effective extracts were(More)
