摘要 目的同时测定鱼腥草注射液中萜品烯-4-醇、α-萜品烯醇和甲基正壬酮挥发性成分的含量。方法采用GC法,色谱柱为SE-54毛细管柱(30 mm×0.32 mm,0.25μm),升温程序为:以2℃.min-1从80℃升至120℃,再以10℃.min-1升至200℃,保持5 min。以正十六烷为内标,选用C18固相萃取小柱对样品进行纯化浓集。结果萜品烯-4-醇0.03~0.30 mg.ml^-1线性关系良好(r=0.9996),平均回收率为98.5%(RSD=1.0%);α-萜品烯醇0.01~0.10 mg.ml^-1的线性关系良好(r=0.9998),平均回收率为98.8%(RSD=0.2%);甲基正壬酮0.01~0.10 mg.ml^-1的线性关系良好(r=0.9999),平均回收率为99.9%(RSD=1.8%)。结论所建方法准确、简便、快速,可用于测定鱼腥草注射液中的3种挥发性成分。 OBJECTIVE To simultaneously determine the three main evanescent components in Yuxingcao injection.METHODS GC determination was performed on a SE-54 column(30 m×0.32 mm,0.25 μm),and the programmed column temperature was elevated from 80℃ to 120℃ at 2℃·min-1,and then to 200℃ at 10℃·min-1,kept for 5 min.n-hexadecane was used as the internal standard(IS),and the samples were purified by C18 SPE column.RESULTS A good linearity was obtained within the range of 0.03-0.30 mg·ml^-1(r=0.9996) and the average recovery of terpinen-4-ol was 98.5%(RSD=1.0%).A good linearity was obtained within the range of 0.01-0.10 mg·ml^-1(r=0.9998) and the average recovery of α-terpinenol was 98.8 %(RSD=0.2%).A good linearity was obtained within the range of 0.01-0.10 mg·ml^-1(r=0.9999) and the average recovery of methyl-n-nonylketone was 99.9 %(RSD=1.8%).CONCLUSION This method is accurate,simple,rapid,and can be used to simultaneously determine the three main evanescent components in Yuxingcao injection.
