Study on free radical scavenging efficency of Toddalia asiatica polysaccharides
摘要
Abstract
Objective：To study the antioxidant activity of polysaccharides from Toddalia asiatica.Methods：The research adopted Fenton method and DPPH method to determine the scavenging ability of Toddalia asiatica polysaccharides to ·OH and DPPH· by comparing with VC.Results：In the concentration of 0.2 ~ 0.4mg/mL,the scavenging ability to ·OH was a positive correlation with the concentration of Toddalia asiatica polysaccharides,when the concentration was 0.4mg/mL,the clearance rate of ·OH was 73.7%.In the concentration of 5×10-3 ~ 5×10-1mg/mL,the clearance rate of DPPH· was 13.5% ~ 79.5%,the scavenging ability to DPPH· was also positively correlated with the concentration of Toddalia asiatica polysaccharides,when the concentration was 0.5mg/mL,the clearance rate of DPPH· was 79.5%.Conclusions：Toddalia asiatica polysaccharides had strong antioxidant properties and possessed a clear scavenging effect to ·OH and DPPH·.关键词
