摘要
咳喘片(百喘朋片)是由盐酸麻黄碱与盐酸苯海拉明组成的复方制剂。作者采用碱性条件下一次萃取后,以毛细管气相色谱法同时测定二者含量。正十五烷为内标,内标加校正因子定量。本法操作简便,精密度好,结果可靠。供试品中盐酸麻黄碱与盐酸苯海拉明的回收率分别为100.2%与99.00%。用于供试品测定获得满意的结果。为更好地控制本品内在质量提供了新的方法。
This paper proposed a method for determination ephedrin hydrochloride and diphenhydromine hydroch loride in kechuan pian by capillary gas chromatography.The procedure involves a single extraction.n-Pentadecane was chosen as an ineternal standard.Analysis was carried out on a 12.5m×0.25mmid.fused siliva capillary column coated with OV-101 and FID detector.The method is simple,rapid and aceurate.
