The anti-oxidant activity of polysaccharide CBP3 in Clanis bilineata tsingtauica Mell
The anti-oxidant activity of polysaccharide CBP3 in Clanis bilineata tsingtauica Mell was studied.The results showed that reductive activity of CBP3 had very significantly positive relationship with its concentration,y=0.1433x+0.0029,R2=0.9918;CBP3 had significantly positive relationship with scavenging ratio of O-2.y=10.865x+1.7857,R2=0.9719,IC50=591 μg/mL;CBP3 had very signifieantly positive relationship with scavenging ratio of OH,y=20.129x-12.489,R2=0.9978,IC50=536 μg/mL.From the results it could be concluded that polysaccharide CBP3 in Clanis bilineata tsingtauica Mell had strong antioxidant capacity to have free radical scavenged in vitro.
