生物碱类药物是一类含氮的碱性有机化合物。游离生物碱一般不溶或难溶于水,能溶于有机溶剂。与酸生成盐,则溶于水及含水的醇,不溶或难溶于有机溶剂。对含生物碱类药物通常加入辅料与水火炮制。例如元胡素,镇痛作用的的效成分是元胡素碱。根据有关资料报道,未炮制的生元胡素水煎液只能提取所含生物碱的25.06%,而醋制在相同的煎液条件下,可以提取所
Alkaloids are a class of nitrogen-containing basic organic compounds. Free alkaloids are generally insoluble or poorly soluble in water and soluble in organic solvents. Salts formed with acids are soluble in water and water-containing alcohols and are insoluble or poorly soluble in organic solvents. For alkaloid-containing drugs, it is usually added with auxiliary materials and water fire. For example, Yuanhusu, the active ingredient of the analgesic effect is perhydroskrine. According to relevant data, unprocessed Yuanyuanhu decoction can only extract 25.06% of the alkaloids it contains, while vinegar can be extracted under the same decoction conditions.
