Antioxidant effects of the Petroleum ether extracts of the leaves of Calotrois procera were tested on the basis of scavenging activity of the free radical DPPH (1, 1-diphenyl2-picryl-hydrazyl), reducing power and inhibition of nitric oxide radical . The Petroleum Ether extracts of C .procera showed the highest antioxidant activity and the activity of the extract increased with increasing concen...

Background and objectives: Natural products are one of the major sources for investigations of novel medicines. Zataria multiflora Boiss (ZM) has shown pharmacological activities especially in gastrointestinal tract; however, there are limited studies about its cytotoxicity effects. In this study, the effect of Zataria multiflora was examined on two colon canc...

Background and objectives: Datura innoxiaMilleris one of the two species of Datura (Solanaceae) which grow in Iran. There are many reports of the biological activities of Datura and in the present study the ability of Datura innoxia for inhibiting angiogenesis was evaluated. Methods: The methanol extract and petroleum ether, ...

In this research, we investigated the antidiabetic activity of Vitis elegans rhizome, which is used as traditional treatment for diabetes mellitus. The methanol, chloroform, petroleum ether, and hexane extracts of the plant root were obtained through serial exhaustive extraction and were analyzed by Thin Layer Chromatography (TLC).  Glycogen phosphorylase (GP) assay was done to determine the in...

INTRODUCTION The ethyl ether extract from Aquilegia vulgaris (L.) (Ranunculaceae) contains a lot of phenolic acids. Their hydroxyl groups are capable of donating hydrogen atoms at the initial stage of lipid peroxidation (LPO), which inactivates hydroxyperoxides formed from polyunsaturated fatty acids (PUFAs) and leads to breakdown of the propagation chain. MATERIAL AND METHODS Rats pretreated...

in traditional system of indian medicine, c.bonducella is widely used for its antipyretic, antiperiodic, anticonvulsive, and antiparalytic activities. for assessing anticonvulsant activity, pentylenetetrazole, maximal electro shock, strychnine- and picrotoxin-induced convulsions models were used. diazepam was used as a standard reference for all models except maximal electro shock model, wherei...

Bemisia tabaci is a key virus vector on several crops worldwide. Then, a preventive approach to deal with viral epidemics may be the deployment of repellents or phagodeterrents at earlier stages of plant development (critical period). Thus, the crude extract and four fractions thereof (water, water: methanol, methanol, and diethyl ether) of bitterwood (Quassia amara, Simaroubaceae) were tested ...

Supercritical fluid extract of leaves of Vitex negundo was tested for its antimicrobial potential and was compared with that of ethanol extract, ether extract and hydrodistilled oil of leaves. The chemical constituents of extracts were studied by chromatographic techniques. Extracts were evaluated for antimicrobial potential against bacterial strains like Staphylococcus aureus, Bacillus subtili...
