Spectrofluorimetric Estimation of Scopoletin in Evolvulus alsinoides Linn. and Convulvulus pluricaulis Choisy.
A simple sensitive spectrofluorimetric method was developed for the analysis of total coumarins calculated as scopoletin in the plants Evolvulus alsinoides and Convulvulus pluricaulis. The fluorescent nature of scopoletin proved to be of immense value in the development of the spectrofluorimetric method. The excitation and emission wavelengths for scopoletin were 430 nm and 460 nm respectively ...
متن کاملNew diterpenoids from the aerial parts of Salvia reuterana
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...

متن کاملEvolvulus alsinoides methanolic extract triggers apoptosis in HepG2 cells
Objective: The objective of the present study was to evaluate the cytotoxic potentials of Evolvulus alsinoides in human hepatoma HepG2 cells. Materials and Methods: HepG2 cells were treated with methanolic extract of E. alsinoides at 20, 40 and 80 µg/ml for 24 hr and cytotoxic effect was analyzed by MTT assay. The apoptosis rate was investigated by Hoechst 33342 and annexin V/propidium iodide s...
متن کاملAntihyperglycemic activity of stigmasterol isolated from Bacopa monnieri Linn. aerial parts against alloxan induced diabetic rats
Objective: Firstly to screen the antihyperglycaemic activity of petroleum ether extract (PBM) of Bacopa monnieri. Finally to examine the antihyperglycaemic activity, in-vivo antioxidant potential, effect on glycosylation of hemoglobin, estimation of glycogen content in liver and in-vitro peripheral utilisation of glucose of stigmasterol (ST), a phytosterol isolated from PBM. Methods: Antihyperg...
