Title: Antioxidant Activity of Psammosilene Tunicoides in vitro
Abstract:Objective:To study the antioxidant activity Psammosilene tunicoides in vitro.Method:Antioxidant activities of P.tunicoides were evaluated by the 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging,...Objective:To study the antioxidant activity Psammosilene tunicoides in vitro.Method:Antioxidant activities of P.tunicoides were evaluated by the 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging,[2,2′-azino-bis(3-ethylbenzothiazoline)-6-sulphonic acid]diamonium salt(ABTS) radical scavenging and ferric reducing antioxidant power(FRAP) assay.Results were compared with that of positive controls PG,BHA and BHT.Result:Antioxidant activity of three extracts from P.tunicoides was weaker than that of the positive control PG,BHA and BHA.In the three extracts,Antioxidant activities of ethyl acetate extract was good.ABTS radical scavenging(IC50=40.54 mg·L-1) and ferric reducing antioxidant power 2.42) μmol·g-1] of ethyl acetate extract were strong,followed by the ABTS radical scavenging(IC50=83.38 mg·L-1) and ferric reducing antioxidant power ·g-1] of n-butanol extract,petroleum ether extract was the weakest.Conclusion:Ethyl acetate extract of P.tunicoides had strong antioxidant activity.Read More
