目的 研究贯叶金丝桃不同器官的分泌细胞团分布密度和金丝桃素含量及其相关性,为选择药用成分高的品种和合理的采收部位提供依据。方法 在显微镜下观察透明装片,统计叶、花萼和花瓣中分泌细胞团的分布密度,用 HPL C法分析各器官中金丝桃素含量。结果 根、茎、果实和叶的中部不含金丝桃素类物质,叶缘部分含金丝桃素 0.14 5 6 %,花萼含 0.0 6 5 3%,花瓣含 1.2 6 82 %。结论 具有分泌细胞团的器官或部位含有金丝桃素类物质,且与其分布密度成正相关 ;而不具分泌细胞团的器官或部位,则不含有金丝桃素类物质

Object In order to choose high hypericin content variety and its useful part, the study on the correlation between nodule density of different organs and hypericin content in Hypericum perforatum L was carried out methods The nodule density of leaf, calyx and petal were observed under a Leica DMLB microscope; the hypericin contents of different organs were determined by HPLC Results Hypericin and its derivatives were not obtained from the root, fruit and leaf central part of H perforatum The hypericin contents of leaf margin, calyx, petal were 0 145 6%, 0 065 3%, 1 268 2%, respectively Conclusion The organs and parts with nodules contain hypericin and its derivatives There is positive correlation between the hypericin content and nodule density, but the other organs or parts without nodules don't contain such materials
