pistacia vera l., a member of anacardiaceae family, has been used for sedation and analgesia in traditional medicine. in this study, the antinociceptive and anti-inflammatory effects as well as acute toxicity of the aqueous and ethanolic extracts of p. vera leaves were investigated in mice. the antinociceptive activity was studied using hot plate and writhing tests. the effect of the extracts a...

Phytochemical analysis of Cymbopogon citratus revealed presence of bioactive compounds such as alkaloids, flavonoids, saponins, tannins, phenols, terpenoids etc. Each of the bioactive compounds were estimated and isolated separately by solventsolvent extraction for methanolic and aqueous extracts of Cymbopogon citratus. Saponins content was higher in methanolic extracts of Cymbopogon citratus (...

Bothriochloa laguroides var. laguroides (DC.) Herter, a native bluestem of America, has been shown to produce many biologically active compounds. The allelopathic potential of aqueous extracts from roots, stems and leaves was examined. Lettuce seeds (Lactuca sativa) and maize (Zea mays), the common allelopathy bioassay systems, as well as seeds from two native species, wintergreen paspalum (Pas...

This study was aimed at assessing the DNA damage protective activity of different types of extracts (aqueous, methanolic and acetonic) using an in vitro DNA nicking assay. Several parameters were optimized using the pUC18 plasmid, especially FeSO4, EDTA, solvent concentrations and incubation time. Special attention has been paid to removing the protective and damaging effect of the solvent and ...

We report on screening tests of 66 extracts obtained from 35 marine sponge species from the Caribbean Sea (Curaçao) and from eight species from the Great Barrier Reef (Lizard Island). Extracts were prepared in aqueous and organic solvents and were tested for hemolytic, hemagglutinating, antibacterial and anti-acetylcholinesterase (AChE) activities, as well as their ability to inhibit or activat...

Aqueous, ethanolic and ethyl acetate extracts of 13 plants used in South Africa for the treatment of venereal diseases were screened for antibacterial and antifungal activity. Among the plants tested, Gunnera perpensa, Harpephyllum caffrum, Hypoxis latifolia and Ledebouria ovatifolia showed the best antibacterial activity. The aqueous extracts of Gunnera perpensa and Harpephyllum caffrum were m...

BACKGROUND AND THE PURPOSE OF THE STUDY It has been shown that Nigella sativa L. and Portulaca oleracea L. have many antioxidant components. In the present study, the cytoprotective effect of ethanolic and aqueous extracts of N.sativa and P.oleracea against hemolytic damages induced by free radical initiator, AAPH [2, 2' azobis (2- amidinopropane) hydrochloride] was evaluated. METHODS Hemolys...

Antibacterial activity of acetone, methanol and aqueous extract prepared from some lichen species were evaluated against five bacterial strains viz. Staphylococcus aureus, Escherichia coli, Vibrio cholerae, Shigella dysenteriae. Shigella flexneri The aqueous, methanol and acetone extracts exhibited a variable range of antibacterial activity to bacterial strains. The acetone and methanol extract...

Methanolic and aqueous extracts of Dendrophthoe falcata Linn. leaves which belongs to the Loranthaceae family, were evaluated through DPPH (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. Methanolic and aqueous extracts of Dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...
