设计出测定乌头(Aconitum carmichaeli Debx.)及其炮制品中毒性生物碱含量的简便方法:萃取法分离—离子对萃取—比色法;提出用异羟肟酸反应—三氯化铁试剂显色—比色法代替高氯酸铁试剂显色法测定乌头及其炮制品中酯型生物碱含量;根据两法测得结果,可求得乌头炮制品的去毒指 A simple method to determine the content of toxic alkaloids in Aconitum carmichaeli Debx. and its processed products was designed: extraction method separation-ion pair extraction-colorimetry; proposed reaction with hydroxamic acid-iron trichloride reagent. Color-colorimetric method instead of iron perchlorate reagent colorimetric method to determine the content of ester alkaloids in Aconitum and its processed products; according to the results obtained by the two methods, the detoxification of Aconitum products can be obtained
