川乌(Aconitum carmichaeli De-bx.)草乌(A.kusnezoffii Reichb.)中含多种生物碱,以乌头碱为代表的双酯类生物碱为其有毒成分。炮制生川乌与生草乌在于保证疗效、降低毒性。但总生物碱的含量与毒性并不成平行关系。暂以总生物碱的含量作为品质优劣的评定,以所含乌头碱的最大限量作为制川乌、制草乌的毒性指标,这在生产中与确保用药安全方面都具有实际意义。仪器及药品75—1型紫外分光光度计。(上海分析 Aconitum carmichaeli De-bx. (A.kusnezoffii Reichb.) contains a variety of alkaloids. Acetyl alkaloids represented by aconitine are toxic components. Concocting raw Chuanwu and Shengcaowu is to ensure efficacy and reduce toxicity. However, the total alkaloid content is not in parallel with the toxicity. For the time being, the total alkaloid content was used as a measure of the quality of the product, and the maximum amount of aconitine contained was used as the toxicity index for producing Chuanwu and Qiucao. This has practical significance both in production and in ensuring drug safety. Instrument and medicine 75-1 type UV spectrophotometer. (Shanghai Analysis
