Comparative Analysis of Active Components and Antioxidant Capacity of Different Parts of Blueberry
With the whole fruit,peel and pulp of blueberry as the raw materials,the content and antioxidant capacity of chlorogenic acid,protocatechuic acid,quercetin,vanillic acid,total flavonoids and total phenols are determined by ethanol extraction method and water extraction method.The results show that the active components and antioxidant capacity of different parts of blueberry fruit are significantly different(P＜0.05).The content of total flavonoids and total phenols in blueberry peel is the highest,significantly higher than the content of total flavonoids and total phenols in the other extracts,which is 32.61 mg/g and 26.95 mg/g respectively.The antioxidant capacity of ethanol extracts of various parts of blueberry fruit is significantly higher than that of water extracts,in the order of blueberry peel＞blueberry whole fruit＞blueberry pulp.The content of the main effective components of each part,including chlorogenic acid,protocatechuic acid,quercetin and vanillic acid,is significantly higher in blueberry peel than in blueberry pulp and blueberry whole fruit(P＜0.05),with the highest content of chlorogenic acid and vanillic acid in blueberry fruit.
