| Abstract: | In this study, using ArctiumLappaL peel as raw material, the polyphenol was extracted with different solvents, such as 70% ethanol, chloroform, ethyl acetate and water. The contents and composition of polyphenol from ArctiumLappaL peel were analysed with HPLC. Through the determination of its DPPH- and OH- scavenging ability, the antioxidation of each extracts were compared. The results showed that polyphenol content in 70% ethanol extracts was the highest and had the strongest antioxidant activity. Main co... |
