近年来,由于洋金花用于中药麻醉及防治慢性气管炎等方面,引起了大家的重视。鉴于洋金花和天仙子同属茄科,其主要成分均为莨菪碱及东莨菪碱,我们分别测定其含量,通过含测结果的分析,对洋金花和天仙子二味中药的质量标准提供依据。成分分析:精密称取过40目筛的样品粉末0.1克,置于5毫升容量瓶中,加2毫升用氨水饱和的氯仿溶液冷浸过夜,吸滤提取液,备用。吸取一定量(视样品中含量高低而定)上述提取液,点样于硅胶G薄板上,以氯仿:甲醇(8.5:1.5)为展开剂,展开后
In recent years, due to Yang Jinhua used in traditional Chinese medicine anesthesia and prevention and treatment of chronic bronchitis and other aspects, has attracted everyone’s attention. Considering that Yangjinhua and Tianxianzi belong to the Solanaceae family, their main components are scopolamine and scopolamine. We determined their contents separately. Based on the analysis of the test results, we provided the basis for the quality standards of the two flavor Chinese medicines, Jinjinhua and Tianxianzi. Component analysis: Weigh accurately 0.1 g sample powder of 40 mesh, place it in a 5 ml volumetric flask, add 2 ml of chloroform solution saturated with ammonia water, soak overnight, and filter the extract by suction. Aspirate a certain amount (depending on the level of the sample). The extract is spotted on a silica gel G plate and developed with chloroform:methanol (8.5:1.5) as the developer.
