蓝莓多酚的萃取及抗氧化活性研究
Extraction and Antioxidant Activity of Polyphenols in Blueberries
摘要
Abstract
The effect of solvent and pH on the contents of extractable polyphenols (EPP) and non-ex- tractable polyphenols (NEPP) of blueberries was investigated in this paper. The antioxidant activity of polyphenols was also determined by DPPH system. The results showed that the solvent containing metha- nol, ethanol and acetone can enhance the EPP contents, especially 500/0 ethanol. The NEPP contents i- solated by the hydrolysis of sulfuric acid were much higher than that of EPP. There is a good correlation between the antioxidant activity and the EPP content. The yield of EPP increased with the decreasing of pH.关键词
