摘要
通过采用高效液相色谱法和紫外分光光度法,分别测定不同生长期黔产天平山淫羊藿和粗毛淫羊藿叶中黄酮类成分的含量变化,确定淫羊藿药材合理的采收期.结果为不同生长期淫羊藿叶中淫羊藿苷和总黄酮的含量有较大差异,花期>果期>花前期>果后期,从淫羊藿药材的品质、产量和可持续利用角度出发,其生产应以花期至果期(4~5月)采收为好.
To determine the change of flavonoid contents of Epimedium myrianthum and Epimedium acuminatum in Guizhou for different growth phase,HPLC and UV were employed.Then reasonable time for collecting was confirmed.The results showed that there are great distinctions of icariin and total flavonoid contents for different growth phase,behaving as: flower period>fruit period>before flower period>after fruit period.Thus it is better to collect the Epimedium herbs between flower period and fruit period(from A...
