Phytochemical analysis of Pfaffia glomerata inflorescences by LC-ESI-MS/MS.
Pfaffia glomerata contains high levels of β-ecdysone, which has shown a range of beneficial pharmacological effects. The present study demonstrated that inflorescences of P. glomerata contain other important bioactive compounds in addition to β-ecdysone. The identification of compounds from inflorescences using liquid chromatography coupled with electrospray ionization tandem mass spectrometry ...

15 صفحه اولEffect of cadmium on growth, micronutrient concentration, and δ-aminolevulinic acid dehydratase and acid phosphatase activities in plants of Pfaffia glomerata
Pfaffia glomerata (Spreng.) Pedersen plantlets were grown under different cadmium (Cd) concentrations (0, 20, 40, 60 and 80 μM) in a hydroponic system during 7 d. Plant growth, micronutrient, chlorophyll and carotenoid concentrations, as well as δ-aminolevulinic acid dehydratase (ALA-D; E.C.4.2.1.24) and acid phosphatase (AP; E.C.3.1.3.2) activities were analysed. Cadmium concentration in both ...
متن کاملPositive inotropic effect of Murraya koenigii (Linn.) Spreng extract on an isolated perfused frog heart.
Ethanolic extract of fresh leaves of M. koenigii (MKEE) showed a dose dependent positive inotropic effect on isolated frog heart. The responses to MKEE (62.5-1000 microg) were not affected in either way by theophylline, imidazole, propranolol and sildenafil. The change in potassium and sodium concentration did not alter MKEE-induced positive inotropic effect. Lignocaine did not alter the respon...
