The objectives of this study was to evaluate the possible in vitro antioxidant potential and analysis of the active polyphenols in ethyl acetate and methanol extracts of leaves of Leonurus sibiricus L. Alcoholic extraction of Leonurus sibiricus leaf was carried out in two different solvents (ethyl acetate and methanol) on the basis of their different polarity. The in vitro antioxidant efficacy ...

Various extracts of Sarcostemma viminale were screened for central analgesic activity by hot plate test, peripheral analgesic activity by acetic acid-induced writhings, CNS depressant activity by pentobarbitone-induced sleep and locomotor activity testing methods and anthelmintic activity on the earthworms Pheretima posthuma . Results showed that petroleum ether and ethyl acetate extracts h...

Background: Efficacy of Centella asiatica on incision and burn wounds are not sufficiently known. In this study we evaluated[SYG1] wound healing activities of different extracts of Centella asiatica, namely hexane, ethyl acetate, methanol, and water extracts, in incision and partial-thickness burn wound models in rats. Results: On day 7 post-wounding, tensile strength of incision wound in all e...

In the present study, coarse powder of Scindapsus officinalis (Roxb.) Schott. fruit was extracted successively using hexane, chloroform, ethyl acetate and 50% ethanol. The ethyl acetate and 50% ethanolic extracts were investigated for its antioxidant activity by using nitric oxide and DPPH radical scavenging methods. The IC value was also calculated. Ascorbic acid was used as standard. Both the...

Solvent extracts of Rhus verniciflua Stokes wood were made using decompressing inner ebullition, and a Box-Behnken design was used to optimize extraction conditions to produce an extract that inhibited tyrosinase activity. The chemical compositions and inhibition rates were determined in extracts made with petroleum ether, ethyl acetate, n-butanol, and an aqueous fractionation. The ethyl acetat...

The main goal of this study was to evaluate antioxidant activity of Vitex agnus-castus aerial parts and also to investigate the main phytoconstituents in the plant extracts. Nhexane, dichloromethane, ethyl acetate and methanol 80% extract were tested for free radical scavenging activity on model reaction with stable 2,2-diphenyl-1-picrylhydrazyl radical (DPPH). The results showed that ethyl ace...

BACKGROUND Traditionally GS is used to treat diabetes mellitus. Drug-herb interaction of GS via cytochrome P450 enzyme system by substrate cocktail method using HLM has not been reported. OBJECTIVE To evaluate the in-vitro modulatory effects of GS extracts (aqueous, methanol, ethyl acetate, chloroform and n-hexane) and deacylgymnemic acid (DGA) on human CYP1A2, 2C8, 2C9, 2D6 and 3A4 activitie...

A phytochemical study on the flowe r of Calotropis gigantea (Linn.) using silica gel column chromatography and preparative thin layer chromatography, led to the first time isolation of Di-(2-ethylhexyl) phthalate (compound 1) and anhydrosophoradiol-3-acetate (compound 2). The structures of these compounds were confirmed by spectroscopic analyses (IR, HRTOFMS and NMR). The antibacterial and anti...

In the present study, the antioxidant potential of the crude methanol and its fractionated extracts (hexane, ethyl acetate and water) of the rhizomes of Alpinia mutica was investigated, employing four different assays. The antioxidant assays used were 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, β-carotene bleaching, superoxide dismutase (SOD) and the reducing power assays while th...

BACKGROUND Hoodia gordonii products are widely commercialized for anti-obesity purposes; however, minimal research is available on the other health properties demonstrated by this popular herbal plant. METHODS H. gordonii crude extracts (ethanol and ethyl acetate) were assayed for in vitro anti-HIV-1 protease (PR), reverse transcriptase (RT) and integrase activity. The 2,2-diphenyl-1-picrylhy...
