目的建立利胆排石片中厚朴酚、和厚朴酚的含量测定方法。方法采用GC法,二甲基聚硅氧烷毛细管色谱柱,载气:氮气,检测器:FID。结果回归方程厚朴酚、和厚朴酚分别为Y=94.12 X+11.28,r=0.9999;Y=135 X+18.21,r=0.9999。结果表明,厚朴酚、和厚朴酚分别在0.014 82~1.482、0.021 03~2.103 mg·ml-1范围内具有良好的线性关系。回收率厚朴酚、和厚朴酚分别为99.6%、99.8%,各成分加样回收率均符合要求。结论该方法简便快捷,准确、重复性好,灵敏度高,可用于建立利胆排石片的定量质量标准。 Objective To establish a method for the determination of honokiol and honokiol in Lixia Pai tablet. Methods GC method, dimethyl polysiloxane capillary column, carrier gas: nitrogen, detector: FID. Results The regression equation honokiol and honokiol were Y = 94.12 X + 11.28, r = 0.9999; Y = 135 X + 18.21, r = 0.9999. The results showed that there was a good linear relationship between magnolol and honokiol in the range of 0.014 82-1.482 and 0.021 03-2.103 mg · ml-1, respectively. The recoveries of magnolol and honokiol were 99.6% and 99.8%, respectively, and the recoveries of all components were all in accordance with the requirements. Conclusion The method is simple, rapid, accurate, reproducible and sensitive. It can be used to establish the quantitative quality standard of Ligustilide.
