[摘要] 目的:建立以RP-HPLC法测定感冒清热颗粒荆芥穗、薄荷中总胡薄荷酮含量的方法。方法:采用Phenomenex Gemini 5u C18 110A色谱柱(4.6 mm×250 mm,5 μm),流动相为:甲醇-水(50∶50),检测波长252 nm,柱温为30℃,流速为1.0 ml/min。结果:胡薄荷酮进样量在0.010 12~0.005 060 μg范围内有良好线性关系,平均加样回收率为99.74%,RSD为0.53%。3批样品中总胡薄荷酮的含量分别为0.063 18、0.063 24、0.063 22 mg/g。结论:本方法灵敏、准确,专属性强,重现性好,可作为感冒清热颗粒荆芥穗、薄荷中总胡薄荷酮的含量测定方法。

[Abstract] Objective: To establish the method for determination of pulegone of schizonepeta spike and mentha haplocalyx in Ganmaoqingre Granule. Methods: The analytical column Phenomenex Gemini 5u C18 110A (4.6 mm×250 mm, 5 μm) was used. The mobile phase was composed of methanol-water (50∶50) at a flow rate of 1.0 ml/min. The wavelength of UV detector was 252 nm and column temperature was 30℃. Results: The linear ranges of pulegone was 0.010 12-0.005 060 μg. The average recovery was 99.24% with RSD of 0.53%. The total contents of pulegone in three batches of samples were 0.063 18, 0.063 24, 0.063 22 mg/g respectively. Conclusion: This method is sensitive, accurate, exclusive. It can be applied to determine the content of pulegone of schizonepeta spike and mentha haplocalyx in Ganmaoqingre Granule.

感冒清热颗粒由荆芥穗、薄荷、防风、柴胡、葛根、苦地丁等组成,具有疏风散寒,解表清热的作用,用于风寒感冒,头痛发热,恶寒身痛,鼻流清涕,咳嗽咽干等。其标准收载在《中国药典》2010年版,原来质量标准有葛根中葛根素的含量测定方法[1]185。方中君药荆芥穗具有散风湿、利咽喉、解表散风、透疹的作用[2],用于感冒、头痛、麻疹、风疹,疮疡初起。其有效成分胡薄荷酮具有抗炎的作用[3]。有报道[4-5]对其中的防风、葛根进行升麻苷、5-O-甲基维斯阿米醇苷和葛根素的含量测定,但未见有报道君药荆芥穗的含量测定。荆芥穗和薄荷均含有胡薄荷酮成分,为能有效控制制剂中总胡薄荷酮的含量,本文现参照《中国药典》2010年版荆芥穗的含量测定方法[1]217,采用高效液相色谱法测定荆芥穗和薄荷中总胡薄荷酮的含量,并对本实验方法进行方法学的研究,为更有效地控制该成药的质量提供借鉴方法。
