Objective To establish the identification and content determination methods of Qibaixiao Ointment, to enhance thequality controllability of Qibaixiao Ointment. Methods Thin layer chromatography method (TLC) was used for qualitative identifica-tion of Coptis chinensis Franch, Bovis calculus Artifactus. Using high performance liquid chromatography (HPLC) was used for con-tent determination of Berberine hydrochloride. Results The TLC spots were clear spots with less negative interference, well separatedand good reproducibility. Berberine hydrochloride showed a good linear relationship in the range of 1. 28 –38. 4 ug. The regression e-quation was: Y =49873. 84X -554.74 (r = 1). The RSD values of precision, repeatability and stability experiments were 0. 41% ,0. 38% , 1. 8%. The average recovery rates was 98. 88% –101. 23% with RSD was 0. 95% (n =7). Conclusion The qualitative i-dentification method and content determination method established method in this study for Qibaixiao Ointment are easy to operate withgood reproducibility and accurate, reliable. It can be used to evaluate the quality of Qibaixiao Ointment. |
