摘    要:目的:建立蒙药六味安消散(阿木日-6)中君药-土木香所含主要成分-异土木香内酯的含量测定方法,为蒙药六味安消散的质量控制提供科学依据。方法:采用美国Trace DSQⅡ型气相色谱仪,柱子:TR-WAX;柱箱温度:起始50℃,停留0 min,升温速率20℃/min,最终温度250℃,停留6 min,升温速率5℃/min,最终温度280℃,停留5 min;载气为氮气,流速为1 mL/min;进样口温度280℃;FID检测器,温度为300℃。结果:异土木香内酯在0.01-0.20 mg/mL范围内呈良好的线性关系,R2=0.9993,平均回收率为99.52%,RSD为2.00%。结论:该方法简便、快速、准确,重现性好,可为六味安消散的质量控制提供方法。

关 键 词:六味安消散  异土木香内酯  含量测定  气相色谱法

Abstract:Objective: To establish a method for the determination of iso-alantolactone in Liuwei anxiao san. Methods: GC( Gas Chromatography) was performed on TR- WAX capillary column( 30m×0. 25mm×0. 25μm) with nitrogen as the carrier gas. The column temperature was programmed from50℃( holding 30min) at a rate of 20℃ / min to 250℃( holding 6min) and then at a rate of 5℃ / min to280℃ finally. The injector temperature was 280℃. The detector temperature was set at 300℃.Results: The linear response ranges were 0. 01 - 0. 20 mg / mL( R2= 0. 9993)( n = 6); the mean recoveries were 99. 52%. Conclusion: The method is simple,quick and accurate. It is suitable for quality control of this preparation.
Keywords:liuwei anxiao san  iso-alantolactone  content determination  GC
