Quality Control of Compound Cornu Cervi Degelatinatum Tablets / 医药导报

ABSTRACT

Objective To establish a method of quality control for compound Cornu cervi degelatinatum tablets. Methods Thin layer chromatography ( TLC ) was used for qualitative identification of Lonicerae Japonicae Caulis and Pyrola Herba in the preparations. High performance liquid chromatography was used to determine the content of loganin and chiratin in Lonicerae Japonicae Caulis and monotropein in Pyrola Herba. Results The TLC spots were clear and specific in the qualitative identification.HPLC determined the content. In the concentration range, monotropein, loganin and chiratin had a good linear relationship with peak area (r>0.999).The mean recovery was 97.2%, 98.4% and 96.0%;RSD was 1.4%, 0.8% and 0.8%. Conclusion The present study employs TLC for quality control and HPLC for quantity control. The methods are simple and accurate, have good reproducibility, and can effectively control the quality of compound Cornu cervi degelatinatum tablets.
