DPPH scaveng activities of ethanolic extracts from Schisandra chinensis extract.To study the Schisandra 

chinensis extract on DPPH free radical scavenging effects.Using rutin and oleanolic acid as the standard 

determination extract total flavone and oleanolic acid;spectrophotometric analysis by scavenging DPPH free 

radical effect,and compared with the Vc.The contents of flavonoids and of oleanolic acid were 49.80 g/mL 

and 235.92 g/mL;with the extracting solution concentration increased,the DPPH free radical scavenging 

rate also increased,showing certain dose-effect relationship;the same concentration,the Schisandra chinensis 

extract and Vc on the DPPH radical removal rates were 77.23% and 94.55%.Schisandra chinensis extract on DPPH 

has strong scavenging effect,is a kind of promising natural antioxidants.
