Abstract:
Objective To isolate and purify the antioxidant compounds from fructus xanthii and to study their antioxidant activity.Methods Compounds were isolated by repeated silica gel,macroreticular resin Diaion HP-20 and Sephadex LH-20 column chromatography and their antioxidant property was determined by scavenging activity to DPPH and ?OH.Results Five antioxidant compounds were isolated from the ethyl acetate extracts of Xanthium sibiricum fruits and their structures were identified as 5,7,3',4'-tetramethoxyisoflavone,myricetin-3'-methyl ether,falcalindiol,1,8-heptadecadiene-4,6-diyne-3,10-diol and 3,4-dihydroxybenzoic acid.Among them,3,4-dihydroxybenzoic acid had the highest radical scavenging activity.Conclusion All above 5 compounds have high antioxidant activities,and antioxidant activity of 3,4-dihydroxybenzoic acid is the highest.
