笔者就炮制对中药主要化学成份的影响,谈“遵古炮制”问题。炮制对含生物碱类药物的影响大多数生物碱几乎不溶于水或难溶于水。而能溶于乙醇等有机溶剂。遇酸生成的生物碱盐却溶于水或易溶于水。生物碱大都是结晶形固体,在高温条件下不稳定。受热可被破坏分解。所以,含生物碱类药物在加辅料炮制时,应使用米醋,黄酒或白酒为好。因米醋是一种稀酸,可使其游离的生物碱
The author will discuss the effects of concocting on the major chemical components of traditional Chinese medicine and discuss the issue of “conforming to ancient methods.” Processing effects on alkaloid-containing drugs Most alkaloids are almost insoluble or insoluble in water. And can be dissolved in organic solvents such as ethanol. The alkaloid salts produced by the acid are soluble in water or soluble in water. Alkaloids are mostly crystalline solids and are unstable at high temperatures. Heat can be destroyed by decomposition. Therefore, with alkaloid drugs in the processing of accessories, should use rice vinegar, rice wine or liquor as well. Since rice vinegar is a dilute acid, it can free alkaloids
