| 目的 研究不同季节柿叶中芦丁和总黄酮含量的动态变化及其抗氧化活性。方法 采用反相高效液相色谱法对不同生长季节柿叶中芦丁含量进行测定；采用紫外分光光度法对不同生长季节柿叶总黄酮含量进行测定；采用1,1-二苯基-2-三硝基苯肼(DPPH)自由基清除能力测定和总抗氧化性能测定,研究不同生长季节柿叶的抗氧化活性。结果 柿叶中芦丁含量在8月份最高；柿叶中总黄酮含量在9月份最高；柿叶的抗氧化活性9月份最强。结论 柿叶中的黄酮类成分含量和抗氧化活性与生长季节有关,柿叶的抗氧化活性还可能与其黄酮类成分含量有关,为柿叶的采收及应用提供了一定的科学依据。 |

| Objective To study the variation of rutin and total flavonoids content and the antioxidant activities in persimmon leaves from different growing seasons.Methods The rutin content was determined by high performance liquid chromatography.The total flavonoids content was determined by UV.The antioxidant activities in persimmon leaves from different growing seasons were evaluated with DPPH radical scavenging assay and total antioxidant assay.Results Rutin and total flavonoids reached their highest contents in persimmon leaves in August and September respetively.The antioxidant activity reached highest in persimmon leaves in September.Conclusions The flavonoid content and antioxidant activity of persimmon leaves were associated with the growing seasons,and antioxidant activity may also be associated with flavonoids content of persimmon leaves,which provided certain scientific basis for the collection and application of persimmon leaves. |
