不同极性梨多酚抗氧化性能的研究
Research on antioxidative activities of different polar polyphenols from pear
摘要
Abstract
Polar polyphenols were extracted from pear using different polar solvents in this study.The antioxidant properties of different polar polyphenols were evaluated by comparing the antioxidant value.The results showed that the peroxide value was 9.43 mmol/kg,and the inhibition rate was 41.86％,added soybean oil with the water layers polyphenols at the fifteenth day.Moreover,the values were 10.19 mmol/kg,and 37.17％,respectively,while adding peroxide value soybean oil with n-butanol layers pear polyphenol.When ethyl acetate layer pear polyphenol was added,the values were changed to be 11.03 mmol/kg and 34.99％ respectively.Significant differences of the antioxidant properties and free radical scavenging abilities of different polar polyphenols from pear could be found in the present studies.The PPO activities order of polyphenols extracted by solvents was water,n-butanol,ethyl acetate,and the PPO activities of polyphenols extracted from pear increased accordant with the solvents polarity increasing.关键词
