采用反相高效液相色谱法分析了宝兴淫羊藿Epimedium davidi的根茎、茎、叶中总黄酮及淫羊藿甙含量在花前期、花期、果期及倒苗前期四个不同物候期中的动态变化。结果表明,植株各部位中总黄酮及淫羊藿甙的含量除花前期中根茎的总黄酮含量高于叶外,均为叶>根茎>茎;各物候期成分含量高低顺序为花期≥果期>花前期>倒苗前期。提示淫羊藿的药材生产,从合理利用、保护资源的角度出发,以利用地上部分为好,以花期至果期(5～6月)采收质佳。
The contents of total flavonoids and epimedium in the roots, stems and leaves of Epimedium davidi in four different phenophases of pre-harvest, flowering, fruiting, and inverting seedling stages were analyzed by RP-HPLC. Dynamic changes. The results showed that the contents of total flavonoids and epimedium in all parts of the plant were higher than those in leaves except for the content of total flavonoids in the early flowering stage. They were leaves> rhizome> stem; the order of the content of each phenophase was the flowering period ≥ fruit period. > Pre-flowering> Early seedlings. It is suggested that the production of medicinal herbs from Epimedium should be based on the rational use and protection of resources, and that it is better to use the above-ground parts and to harvest from the flowering period to the fruiting period (May to June).
