ilex spinigera (aquifoliaceae) plant is an evergreen tree or shrub with thick glossy dark green leaves and red fruits. this plant has medicinal properties and has been used traditionally in northern iran for malaria treatment. the aim of this work is to evaluate the antioxidative activities and the inhibitory effect of i.spinigera on the oxidation of dna. we have found no reports about the popu...

In Vitro Antimicrobial and Antioxidant Activity of Chitosan Isolated from Podophthalmus VigilK. Prabu E. Natarajan

the aim of the study is to examine in-vitro antioxidant and antimicrobial activity of the acetonic and methanolic extracts of the mushrooms boletus aestivalis, boletus edulis and leccinum carpini. antioxidant activity was evaluated by using free radical scavenging activity and reducing power. in addition, total content of phenol and flavonoid in extracts were determined as pyrocatechol equivale...

The in vitro total antioxidant assay, total phenolic content, DPPH assay, FRAP assay of the acetone extracts from four centric diatoms (Chaetoceros simplex, Skeletonema costatum, Odontella mobiliensis, Coscinodiscus centralis) and three pennate diatoms (Nitzschia closterium, Pleurosigma angulatum and Navicula sp.) were performed. The centric diatom, O. mobiliensis was found higher amount of phe...

pathogenic infections and inflammation are very common ailments humans suffer. upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. in line with these developments the synthesis of n-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4h-1...

PURPOSE The paper tried to systematically investigate the in vitro antioxidant activity of Rhizoma Cibotii (RC) for the first time. METHOD The methanol extract from RC (MERC) was prepared then systematically investigated by various antioxidant assays, including: DPPH• (1, 1-diphenyl-2-picrylhydrazyl radical), ABTS•(+) (3-ethylbenzthiazoline-6- sulfonic acid diammonium salt radical), •O2- (sup...
