- 摘要:
- 以4个桃品种为试材，对不同发育期的果实中总酚类物质的含量及抗氧化活性进行测定，以揭示不同品种桃果实成熟过程中多酚类物质与抗氧化活性的变化规律。结果表明：各品种桃果实中总酚含量和抗氧化活性均在采摘初期最高，随着果实的成熟呈逐渐下降趋势。高效液相色谱（HPLC）分析结果显示，绿原酸、儿茶素、新绿原酸、表儿茶素是各品种桃果实中最主要的酚类物质，其含量在桃果实发育过程中与总酚含量变化规律一致，也呈下降趋势。
- Abstract:
- Phenolic compounds and antioxidant capacity were studied in four cultivars during their different fruit development stages.In order to discover the dynamic changes of phenolic compounds and antioxidant capacity.The results showed that the contents of total phenolic content and antioxidant capacity were the highest at young fruit period and decreased during fruit development.Chlorogenic acid，catechins，epicatechins，neochlorogenic acid were detected by high-performance liquid chromatography and also showed that they had a descending trends with development of peach as well as phenolic compounds.
