广东紫珠不同部位、不同产地金石蚕苷、连翘酯苷B含量变化研究

摘要

Objective] This study was conducted to determinate the contents of poliu-moside and forsythoside B in Calicarpa kwangtungensis, so as to reveal the distri-bution of two index components (poliumoside and forsythoside B) in the plant and to compare the contents of these components in the medicinal materials from differ-ent habitats. [Methods] Comparison and analysis of the contents of the two target components in different parts (root, branch, leaf and fruit) of Calicarpa kwangtun-gensis from the same habitat and in Calicarpa kwangtungensis from different pro-duction areas were performed according to the pharmacopoeia standard. [Result] The highest content of poliumoside wasdetected in fruit, and the content of forsythoside B was the highest in the branch. The contents of the two kinds of components were in order of branch> fruit> leaf>root; The contents of the compo-nents were four times higher than China pharmacopeia (0.5%) in Jian, Tonggu, Anyuan, and Ganzhou of Jiangxi Province and the fifth area, Taijiang County of Qiandongnan Miao and Dong Autonomous Prefecture (QMDAP), among which Ganzhou and Taijiang showed the highest contents. [Conclusion] The differences of poliumoside and forsythoside B were obvious in different habitats and different parts of Calicarpa kwangtungensis.%[目的]测定广东紫珠不同部位和不同产地中金石蚕苷、连翘酯苷 B 两种指标性成分含量。[方法]采用药典方法对贵州黔东南州台江县种植的广东紫珠不同部位和主要种植区域中金石蚕苷、连翘酯苷 B两种指标性成分含量进行测定，揭示指标成分在广东紫珠植物中的分布；同时，测定不同种植区中指标成分含量变化情况。[结果]果实中金石蚕苷含量最高，枝中连翘酯苷 B含量最高，两种指标成分的总量枝中最高，依次是果实、叶和根；江西吉安市、江西宜春铜鼓县、江西萍乡市安源区、江西赣州市宁都县和贵州黔东南州台江县5个种植区所产广东紫珠药材指标成分均高于药典要求（0.5%）4倍以上，其中江西赣州市宁都县和贵州黔东南州台江县含量较高。[结论]不同部位，不同产地广东紫珠中金石蚕苷、连翘酯苷B两种指标性成分含量差异显著。
