贵州主栽蓝莓品种活性成分及其抗氧化活性评价
Evaluation of bioactive compounds and antioxidant activity of major blueberry cultivars in Guizhou province
摘要
Abstract
To investigate the phenolics compounds and antioxidant activity of major blueberry cuhivars in Guizhou province,the phenolics compounds,polyphenols,total flavonoids,anthocyanin,and in vitro antioxidant activity of four cultivars in Guizhou province were analyzed using Pearson's correlation analysis.The results indicated that the major phenolic compounds,including gallic acid,epcatechin,rutin,p-coumaric acid,quercetin,catechin,ellagic acid,chlorogenic acid and ferulic acid in the tested blueberry fruits were the highest.The contents of phenolic compounds were significantly different in the 4 cultivars (P ＜ 0.05),the gallic acid,ferulic acid and total flavonoids of Powderblue was the highest,the chlorogenic acid,ellagic acid and rutin of Gardenblue was the highest,the quercetin and anthocyanin of Baldwin were the highest,the catechin,epcatechin,p-coumaric acid and polyphenols of Bright Well was the highest.Antioxidant activities of four cultivars were significantly different (P ＜ 0.05),and the highest antioxidant activity of Bright Well was the highest.The difference of phenolic compounds on the antioxidant activity was significant (P ＜ 0.05).Chlorogenic acid has a strong contribution to FRAP value.The ferulic acid,total polyphenols and total flavonoids has a strong contribution to TRAP value;the gallic acid has a strong contribution to DPPH value,the anthocyanin has a strong contribution to ABTS value.The antioxidant potential composite index (ACI)showed a significant positive correlation with the content of epcatechin and p-coumaric acid (P ＜ 0.01).关键词
