中药烧烫伤凝胶质量标准的色谱研究

Chromatographic Methods of Shaotangshang Gel

  • 摘要: 建立烧烫伤凝胶的色谱(TLC和HPLC)质量标准.采用薄层色谱法(TLC)对烧烫伤凝胶中黄连、黄柏、大黄、黄芩进行了定性鉴别,并用高效液相色谱法(HPLC)对烧烫伤凝胶中有效成分盐酸小檗碱进行含量测定.盐酸小檗碱含量测定的线性范围为26.64~133.20μg/mL,r=0.9997,平均回收率为96.77%,RSD为1.6%.定性鉴别和含量测定方法简便可靠,重复性好,可有效的控制烧烫伤凝胶的质量.

     

    Abstract: Objective: to establish the chromatographic methods of Shaotangshang gel for control the quality standard of Chinese medicine. Methods: TLC was performed to identify Rhizoma coptidis,Cortex phellodendri chinensis,Radix et rhizome rhei,Radix scutellariae.HPLC was used to determine content of Berberine hydrochloride. Conclusion: the characteristic of identification by TLC was distinct and highly specific and the quantification method had the linearity range of 26.64~133.20 μg/mL,r=0.9997.The average recovery was 96.77% and RSD was 1.6%.The methods of identification and quantification are simple,realizable and reproducible.It could be used effectively for the quality control of Shaotangshang gel.
