跌伤灵贴膏的质量标准研究

Quality Standard for Dieshangling Plasters

目的:建立跌伤灵帖膏的质量标准。方法:采用气相色谱法鉴别跌伤灵贴膏中的樟脑、冰片、水杨酸甲酯,同时采用气相色谱法对跌伤灵贴膏中的薄荷脑进行含量测定。结果:制定的樟脑、冰片、水杨酸甲酯气相鉴别方法专属性强;制定了气相色谱法测定薄荷脑的含量,在0.032 8~0.327 8 mg·ml^(-1)(r=0.999 98)有良好的线性关系,平均回收率为100.29%,RSD=1.78%(n=7)。结论:所建立的方法操作简单、专属性强、重现性好,可作为跌伤灵贴膏的质量控制方法。

Objective： To establish the quality standard fnr Dieshangling plasters. Methods ： GC was employed in the identification of camphor, borneol and methyl salicylate. GC was applied in the determination of menthol in Dieshangliug plasters using naphthalene as the internal standard. Results： The GC characteristics of camphor, borneol and methyl salicylate were obvious and highly specific. The linear range of menthol was within 0. 032 8-0. 327 8 mg·ml^-1 （ r = 0. 999 98）. The average recovery was 100.29% and RSD was 1.78% （n = 7）. Conclusion： The method is simple, accurate and reproducible, and suitable for the quality control of Dieshangling plasters.
