石榴叶多酚的纯化及抗氧化活性研究
Purification and Antioxidant Activity of Polyphenols from Punica granatum L.
摘要
Abstract
The macroporous resin was choosen for separating crude polyphenols from the leaves of Punica granatum L., three different purity of polyphenols from Punica granatum L. leaves were got,compared with Rutin,three different puri⁃ty of polyphenols from Punica granatum L. were evaluated with different antioxidant tests. The results showed that with sample solution concentration of 2.5 mg/mL,pH=4,feeding speed of 2 mL/min,ethanol concentration of 60%,elution volume of 1.7 BV~2.0 BV,the purity of CPPL was 62.44%,the purity of purified polyphenols of crude polyphenols from Punica granatum L. leaves was 92.83%which was further improved by PA. The results of oxidation stability analysis of polyphenols in Punica granatum L. leaves were showed that it had the better effect in scavenging free radical and reduc⁃ing power with the higher purity,compared with rutin,reducing power and nitrite scavenging activity of purified polyphe⁃nols from Punica granatum L. leaves was stronger.关键词
