历代认为半夏有毒,内服时对粘膜有刺激性,古时有戟人咽,令人呕的记载,故一般须经炮制后入药。为进一步探讨半夏的炮制原理,我们对半夏及其不同炮制品中已知化学成分总生物碱、氨基酸的含量进行了实验研究。 The past generations believed that Pinellia was poisonous and that it was irritating to mucous membranes when taken orally. In ancient times, there were reports of phlegm and nausea, and it was generally recorded as vomiting. Therefore, it was generally required to make medicine after concocting. In order to further explore Pinellia’s principle of processing, we conducted experimental research on the content of total alkaloids and amino acids of known chemical constituents in Pinellia ternate and its different processed products.
