【摘要】 目的:研究并建立咳喘软膏的质量标准。方法:采用显微和薄层鉴别对五味子、白芥子和延胡索进行定性鉴别;用超高液相色谱法(UPLC)测定制剂中白芥子以芥子碱硫氰酸盐计的含量。结果:薄层色谱法定性鉴别斑点清晰,专属性强,阴性对照无干扰;芥子碱硫氰酸盐浓度在0.995~1.194μg线性关系良好,r=0.999 2,加样回收率为96.1%,RSD为1.65%。结论:咳喘软膏质量标准方法准确,精密度高,切实可行。更多还原

【Abstract】 Objective: To establish the quality standards of Kechuan ointment. Methods: The Schisandrae Chinensis Fructus,Sinapis Semen and Corydalis Rhizoma were qualitatively identified by microscopy and TLC. Sinapine thiocyanate was quantitatively determined by UPLC. Results: The spots of the TLC were clear and had no negative interference. The linear of the berberine hydrochloride was 0. 995-1. 194μg( r = 0. 9992). The Sample recovery rate was 96. 1%,and RSD was 1. 65%. Conclusion: The method is accurate,precise,and feasible.更多还原
