摘    要:目的探讨建立薄荷药材的提取和含量测定方法。方法以薄荷脑为指标成分,采用DM—FFAP弹性石英毛细管柱,初始柱温为120℃,以2℃/min升温至140'C,然后以15℃/min升温至220℃,保持5min。比较索氏提取、加热回流、超声提取法的差异,并优选最佳提取方法。结果最佳提取工艺:加10倍量无水乙醇溶液85℃回流提取1h。薄荷脑在34.034~343.04μg/ml浓度范围内线性关系良好,平均回收率为99.00%,RSD=1.87%(n=6)。结论本文所建立的提取和含量测定方法快速简便、结果可靠,可为薄荷药材质量控制提供科学依据。

Abstract:Objective To explore the methods for extraction and content determination on Mentha haplocalyx Briq. Methods Menthol was as the index components.DM-FFAP chromatographic column was applied,with initial temperature set at 120℃,then heated up to 140℃ at the speed of 2℃/min,then heated up to 220℃ at the speed of 15℃/min, then maintained the temperature at 220℃ for 5 minutes.The optimal extraction method was selected based on comparison of Soxhlet extraction,heat reflux extraction and ultrasonic extraction. Results The study identified the optimal extraction process: adding 10 times amount of anhydrous ethanol solution then heat reflux extraction under 85℃ water bath for 1 hour.Menthol had good linear relation at the concentration of 34.034-343.04 μg/ml,with average recovery rate of 99.00% ,RSD=1.87% (n=6). Conclusion The extraction and content determination methods developed in the study are quick,simply,eonveninent and reliable,providing scientific basis for quality control of Mentha haplocalyx Briq.
Keywords:Extraction  Content determination  Menthol  Mentha haploedyx Briq
