麻黄的地上部分在中药中作为发汗、解热、镇咳、抗炎的常用药。其药效根据植物部位的不同而异。一般来说,地上部分的节间有发汗作用,节及根具止汗作用。作者首先就传统认为麻黄的节间与节药效不同的角度着眼,研究了节间与节的各种药理作用。结果说明两者药理作用虽有不同,但无论哪一部分均含有麻黄素类生物碱。作者又采用等速电泳法测定了十一种麻黄的节间与节中 The aerial part of ephedra is commonly used as a common drug for sweating, antipyretic, antitussive and anti-inflammation in Chinese medicine. Its efficacy varies according to the plant parts. In general, the internodes of the ground have perspiration, and the knots and roots have antiperspirants. The author first focused on the traditional view that the internodes and the efficacy of Ephedra were different, and studied the various pharmacological effects of internodes and festivals. The results showed that although the pharmacological effects of the two are different, no matter which part contains ephedrine alkaloids. The authors also determined the internodes and nodes of eleven species of ephedra using isotachophoresis.
