【摘要】 <正>乌头生物碱各成分毒性差异很大,其中乌头碱的毒性为其它成分的100-2000倍,是引起中毒和死亡的主要原因。乌头生物碱种类多,在煎煮或泡制过程中易水解产生不同水解产物,进入体内后代谢情况又不明,因此采用液相色谱方法对体内检材乌头碱成分仅靠保留时间确定依据不足,定量工作更是无法开展。但在现实生活中炮制后的乌头植物可入药,且炮制过的乌头植物也可检出少量原碱。遇到体内检材中检验出乌头生物碱成分时,办案单位往往希望有一个量的甄别。经查阅资料,未见体内检材(如血、肝、尿等)中乌头碱含量的报道。我们应用LC-MS,采用646.4单离子扫描方式对实际案例血中乌头碱含量进行了测定,为今后的进一步研究和同行提供数据积累。更多还原

【Abstract】 Aconitum alkaloids consist of a group of compounds. The toxicity of the compounds make a great difference. Aconitine is more deadly poisonous than the others. The quantity of aconitine is crucial for judging case. This article established an analysis method for aconitine in the human body with LC - MS instrument. The quantitative analysis method was applied in several cases and proved to be highly effective and precise.更多还原
