【Abstract】 The abilities of scavenging O₂^-and · OH of crude extract,the portion extracted by n-butanol and the aqueous portion remained of bamboo leaves were studied by chemiluminescence.The results showed that all of the three extracts had strong antioxidant activity.Crude extract was higher than the portion extracted by n-butanol.The antioxidant effective positions of the aqueous portion were further tested qualitatively and found to be probably tannin and δ-OH-Lys etc.From the above,we can draw the following conclusion:the extract of bamboo leaves was a complex and synergistic mixture.It was no effective on antioxidant activity to purify further.更多还原
