在中国,三棱作为祛瘀血药而使用,其原植物为黑三棱(Sparganiaceae)科的黑三棱(Sparganium stoloniferum)、小黑三棱(S. simplex)、细叶黑三棱(S. stenophyllum)、莎草科的荆三棱(Scirpus flaviatilis),其所含成分除挥发油、淀粉外,其它成分尚未搞清。作者对这些生药进行了化学方面的研究,此次就对荆三棱的研究报告如下。先将荆三棱以CHCl_3提取,以甲醇提取,再将甲醇提取物分 In China, Trigonellae is used as a blood-threatening drug. Its original plant is Sparganium stoloniferum, S. simplex, and trilobal black-triangle (Spargananiaceae). Stenophyllum, Scirpus flaviatilis, which contains components other than volatile oils and starches, has not yet been identified. The authors carried out chemical research on these crude drugs. This time, the research report on Jing Sanling is as follows. First, extract the Jingsanling with CHCl_3, extract with methanol, and then separate the methanol extract.
