摘要: 通过研究不同采摘时期莼菜多酚的含量及其抗氧化能力,确定采摘莼菜的最佳季节。采用紫外分光光度法测定莼菜多酚含量,选用DPPH·法、ABTS法、FRAP法对提取物进行体外抗氧化活性研究。结果表明:6月份采摘期多酚含量最高为28.045±1.654 mg/g,10月份次之为12.796±2.492 mg/g,8月份多酚含量最低为16.342±1.198 mg/g,不同采摘时期的莼菜提取物均具有抗氧化活性。本研究可为莼菜不同采摘期的工艺优化和产品质量监督提供必要的数据基础和行业指导。

Abstract:

The best season for picking Brasenia schreberi was determined by studying the content of polyphenols and antioxidant capacity of B. schreberi at different picking periods.Ultraviolet spectrophotometry was used to determine the content of polyphenols in B. schreberi.DPPH,ABTS and FRAP methods were used to study the in vitro antioxidant activity of the extracts.The results showed that the highest polyphenol content in June was 28.045±1.654 mg/g,followed by 12.796±2.492 mg/g in October,and the lowest was 16.342±1.198 mg/g in August.B. schreberi in different picking periods The extracts all have antioxidant activity.This research can provide necessary data foundation and industry guidance for the process optimization and product quality supervision of B. schreberi in different picking periods.

Key words: Brasenia schreberi, picking periods, content of polyphenols, antioxidant activity
