The free-radical-scavenging activities of various solvent extracts of Microcos paniculata were evaluated through in vitro model systems, such as 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) and Co (II) EDTA-induced luminol chemiluminescence by flow injection. In all three of these systems the ethyl acetate (EtOAc) extract showed the highest fr...

The leaves, barks, flowers, fruits and seeds of Calophyllum inophyllum are widely used in traditional practices. Here in the present study, we aimed to evaluate in vitro antioxidant potential of leaf aqueous and methanolic extracts of C. inophyllum in relation to total phenol and flavonoid contents. DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging and ferric (Fe) reducing power was ...

The aim of the present study is to evaluate the antioxidant and proliferative effects of aqueous and ethanolic extracts of Symphytum officinale. Antioxidant activities of extracts were determined by 2,2diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, superoxide radical scavenging and Folin-Ciocalteu assays. Proliferative effects of the extracts were evaluated on 3T3 Swiss albino mouse fibro...
