【摘要】 采用ＧＣ－ＭＳ联用技术，对尿中的沙丁胺醇（ｓａｌｂｕｔａｍｏｌ）进行分析。实验表明，口服一片沙丁胺醇（２．４ｍｇ），可于２４ｈ从尿中排泄，且以游离形式为主。样品提取时，控制溶液ｐＨ为８．８时，提取率较高。本方法对沙丁胺醇定性简单、快速、准确.更多还原

【Abstract】 Salbutamol(2.4mg) was administrated to a healthy male. The urine wasanalysed by GC-MS.95%of the drug was excreted in 24 h in unconjugated form.The pH of urinewas shown to strongly affect the extraction rate,good recovery was obtained at pH 8.8.With thismethod,salbutamol can be determined simply,quickly and accurately.更多还原
