Present study was designed to compare antioxidant and DNA damage protection of Soxhlet assisted (80% methanol) extract (SEMC) with microwave assisted (80% methanol) extract of Michelia champaca Linn. (MEMC). The in vitro antioxidant activity of SEMC and MEMC were tested for DPPH, hydroxyl radical (OH) by deoxyribose, lipid peroxidation and reducing power capacity. The extracts were also tested ...

the antioxidant activity of the different extracts and fractions of aerial parts of otostegia persica (burm.) boiss. were evaluated using beta-carotene bleaching and lipid peroxidation methods. the inhibitory activity of the plant extracts on the peroxidation of linoleic acid were measured by ferric thiocyanate method in comparison to methanolic extracts of green tee, ginkgo biloba, vit.e and b...

in recent years the use of toxic and carcinogenic synthetic antioxidants are recommended to get limited. therefore, the use of natural resource materials as an alternative substitution for synthetic compounds is indispensable. throughout the present study, antioxidation properties of fennel essential oil, at different concentrations containing 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8 mg/ml in ...

The effects of four calcium channel blockers (nicardipine, nifedipine, verapamil, and diltiazem) on free radical injury in cultured endothelial cells were studied and compared with those of butylated hydroxytoluene. When the cultured cells were exposed to a superoxide and hydroxyl radical generating system for up to 60 minutes, lipid peroxidation occurred, and cellular viability decreased by 60...

We investigated in vitro antioxidant activities of 49 endophytic fungi isolated from the liverwort Scapania verrucosa. Based on morphological and molecular identification, the endophytic fungi isolated were classified into seven genera (Hypocrea, Penicillium, Tolypocladium, Chaetomium, Xylaria, Nemania, and Creosphaeria), all belonging to one family (Xylariaceae). By screening with the 2,...

The use of mixed selective solvents provides an effective means to control self-assembly of the all-conjugated diblock copolymer poly(3-butylthiophene)-b-poly(3-hexylthiophene) (P3BHT) into nanostructured morphologies. The solvent and temperature effects on the self-assembly of P3BHT during cooling and subsequent crystallization were explored for the first time. Depending on the poor/good solve...

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...

Curcuma angustifolia also known as ‘haledo’ is commonly found in Sikkim and has many medicinal uses and has been used traditionally since ancient ages. Its rhizome is aromatic and the solvent extract of the rhizome has free radical scavenging activity which was carried out in this study by 2,2-diphenyl-1-picrylhydrazyl DPPH. Hot methanol extract and cold methanol extract of the dried powder of ...
