Considering the indigenous utilization of Quercus incana Roxb., the present study deals with the investigation of antioxidant, free radical scavenging activity, total phenolic content, and antimicrobial activity of Q. incana Roxb. In vitro antioxidant activity of the plant fractions were determined by 1,1-diphenyl-2-picrylhydrazyl and nitric oxide scavenging method. Total phenolic contents were...

Moringa oleifera leaves extracted with methanol and dichloromethane were screened for antioxidant activity. The in vitro cancer antiproliferative and chemopreventive properties were also investigated. Radical scavenging assays with 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2 ́-azino-bis 3ethylbenzothiazoline-6-sulfonic acid (ABTS) were used to determine the antioxidant activity. The antiprolif...

Free radicals are implicated for more than 80 diseases including Diabetes mellitus, arthritis, cancer, ageing etc. In treatment of theses diseases, antioxidant therapy has gained an utmost importance. Current research is now directed towards finding naturally occurring antioxidant of plant origin. In Indian system of medicine Ipomoea fistulosa is an important medicinal plant. The in-vitro antio...

Essential oils of many plants besides having a strong and pleasant aroma also are biologically active as an antioxidant. They have an important economic role in the medical and pharmaceutical industries, aromatherapy and cosmetology, production of natural food flavorings and as natural preservative. A variety of free radical scavenging antioxidants are found in dietary sources like fruits, vege...

This research highlights the photoprotective potential of a traditional medicinal plant, Zanthoxylum rhetsa. The photoprotective effect was measured based on the sunscreen protection factor (SPF value) and UV absorption spectrum of various solvent fractions of the plant. The ethyl acetate fraction had the highest SPF value (13.36±0.12) followed by butanol (8.6±0.08), at a test concentration of ...

The aim of this investigation was to determine the content of total phenolics, antioxidant activity and cytotoxicity of methanol extracts from the aerial parts of 11 Korean medicinal salad plants. The highest total phenolic content of the methanol extracts was found in Aster scaber (17.1 mg 100 g(-1)), followed by Ixeris dentate (16.4 mg 100 g(-1)), Aster yomena (12.0 mg 100 g(-1)) and Sedum sa...
