目的 :建立开胃消食口服液中乙酸龙脑酯含量的气相色谱测定法。方法 :萘为内标物 ,不锈钢柱 ,PEG 2 0M固定相 ,氮气为载气 ,FID检测器。结果 :在该色谱条件下样品中乙酸龙脑酯及内标物萘都能得到很好的分离 ,乙酸龙脑酯的加样回收率为 95 .2 9% ,RSD为 0 .6 1%。结论 :本法灵敏、准确、重现性好 ,可作为该制剂的质量控制指标之一 Objective : To establish a gas chromatographic method for the determination of the content of borneol acetate in Oral Xiaoxiao Oral Liquid. Methods: Naphthalene was used as internal standard, stainless steel column, PEG 2 0M stationary phase, nitrogen as carrier gas, FID detector. RESULTS : Under the conditions of the chromatographic conditions, the naphthyl acetate and the internal standard naphthalene were well separated. The recovery of naphthoyl acetate was 95.29% and the RSD was 0.61%. Conclusion : This method is sensitive, accurate, and reproducible. It can be used as one of the quality control indicators of the preparation.
