目的:建立痤疮散质量控制方法。方法:采用薄层色谱法对制剂中的大黄、白芷和防风进行定性鉴别;采用气相色谱法同时测定制剂中百秋李醇、薄荷脑和冰片的含量。结果:薄层色谱显色清晰且阴性对照无干扰。百秋李醇、冰片、薄荷脑分别在0.020 1~0.805 6 mg·ml~(-1)、0.010 0~0.401 6 mg·ml~(-1)、0.005 1~0.202 8 mg·ml~(-1)浓度范围内呈良好的线性关系,平均回收率(n=6)分别为102.03%(RSD=0.91%)、100.10%(RSD=1.94%)、103.15%(RSD=1.68%)。结论:本法操作简便,结果准确、重现性好,可用于痤疮散的质量控制。
Objective: To establish acne mass control method. Methods: The rhubarb, Angelica dahuricae and windbreak were identified by TLC. The content of berberine, menthol and borneol were determined simultaneously by gas chromatography. Results: Thin-layer chromatography developed clear and negative controls without interference. Plectasol, borneol and menthol in the range of 0.020 1 ~ 0.805 6 mg · ml -1, 0.010 0 ~ 0.401 6 mg · ml -1, 0.005 1 ~ 0.202 8 mg · ml ~ (-1) 1). The average recoveries (n = 6) were 102.03% (RSD = 0.91%), 100.10% (RSD = 1.94%) and 103.15% (RSD = 1.68%), respectively. Conclusion: This method is simple, accurate, reproducible and can be used for quality control of acne.
