西沙诺尼果汁不同极性多酚及抗氧化活性的分析
Antioxidant activity of polyphenols with different polarities from Xisha noni juice
摘要
Abstract
Different polyphenol extracts were obtained from Xisha noni juice using organic solvents with different polarity.Total phenolic content was determined by Folin-ciocalteu method.Antioxidant activity was evaluated by DPPH scavenging assay,ABTS scavenging assay and total antioxidant capacity assay.It was shown that liquid-liquid extraction was a successful method for separating polyphenols with different polarities,and polar polyphenols were dominant in Xisha noni juice.Antioxidant activities of water-soluble fraction is the strongest and there was no significant difference between ethyl acetate-soluble fraction and n-butanol-soluble fraction which were stronger than chloroformsoluble fraction.Antioxidant activity of different extracts was significantly positive correlated with total phenolic content.The polyphenols were the main antioxidant substances.关键词
