目的:建立薄荷药材及饮片中薄荷脑的气相色谱含量测定方法,控制其质量。方法:采用INNOWAX弹性石英毛细管柱(柱长30 m,柱内径0.53 mm,膜厚1μm);程序升温。供试品溶液的制备采用正己烷超声提取。结果:薄荷脑在9.36 ng～4680 ng范围内线性关系良好,平均回收率为97.8%。结论:该方法可行,重复性好,可用于控制薄荷药材与饮片的质量。 Objective: To establish a gas chromatographic method for the determination of menthol in peppermint herbs and Pieces and to control its quality. METHODS: INNOWAX elastic quartz capillary column (column length 30 m, column inner diameter 0.53 mm, membrane thickness 1 μm) was used. The temperature was programmed. Preparation of the test solution using n-hexane ultrasonic extraction. RESULTS: Menthol had good linearity in the range of 9.36 ng to 4680 ng with an average recovery of 97.8%. Conclusion: This method is feasible and reproducible, and can be used to control the quality of medicinal herbs and Pieces.
