中国防己科千金藤属药用植物资源利用研究

本文报道我国防己科18种千金藤属药用植物的资源及化学分析工作:通过薄层检查了17种生物碱在这些植物中的存在情况,测定了每种的根部所含总生物碱的含量以及用CS-910型薄层光密度计测定了其中10种生物碱的含量。结果表明,千金藤属植物是寻找异喹啉类生物碱新资源的对象,特别是有较大形块根的山乌龟亚属是今后生产肌肉松弛剂等药物有价值的原料植物;对千金藤属的化学分类提供了一定的依据。

UTILIZATION OF MEDICINAL PLANT RESOURCES OF THE GENUS STEPHANIA OF THE FAMILY MENISPERMACEAE IN CHINA

The genus Stephania is one of the alkaloid-rich genus of the family Menispermaceae and includes about 50 species distributed in the whole world, among which approximately 32 species has been found in China, and 18 species are used medicinally.In this paper, 18 medicinal plant species in Stephania, their distritution, abundance of resources are reported, and the content of total alkaloid in each plant, the distribution of 17 alkaloids in root and tuberous root and the content of 10 alkaloids. are determined. The result of the present investigation revealed that plants of genus Stephania are abundant sources of isoquinoline types of alkaloids, especially those plants with tuberous roots from subgenus Shan-wu-gui are valuable raw materials for preparation of muscle relaxants. The result also provided some useful data for chemotaxonomy of Stephania genus.
