目的:建立荆花胃康胶丸中3种挥发性成分的含量测定方法。方法:采用Agilent 6890N型气相色谱仪,氢火焰离子化检测器(FID),HP-5MS(30 m×0.32 mm,0.25μm,5%苯甲基硅氧烷)弹性石英毛细管柱,以萘为内标进行测定。结果:在该色谱条件下,驱蛔素、对伞花烃、α-松油烯和内标萘均达到较好分离,在测定范围内线性良好,加样回收率均在100%～103%之间。结论:本法灵敏、准确、重复性好,可用于荆花胃康胶丸的质量控制。
Objective: To establish a method for the determination of three volatile components in Jinghua Weikang capsule. Methods: Agilent 6890N gas chromatograph, hydrogen flame ionization detector (FID) and HP-5MS (30 m × 0.32 mm, 0.25 μm, 5% phenylmethylsiloxane) Internal standard determination. Results: Under the chromatographic conditions, the carciclovir, p-cymene, α-terpinene and internal standard naphthalene were all separated satisfactorily with good linearity in the range of determination. The recoveries of the two compounds were in the range of 100% -103% between. Conclusion: This method is sensitive, accurate and reproducible. It can be used for quality control of Jinghua Weikang capsule.
