Qualitative and Quantitative Methods for Corni Fructus in Guishao Dihuang Pills / 中国药师

ABSTRACT

Objective:To establish the qualitative and quantitative methods for Corni Fructus in Guishao Dihuang pills. Methods:A TLC method was used to identify morroniside and loganin. An HPLC method was used to determine the content of morroniside and lo-ganin in Corni Fructus. Results:The TLC spots were clear with good separation and specificity. The linear range of morroniside was within 0. 010-2. 620 μg (r=0. 999 9) and the average recovery was 102. 75% (RSD=1. 40%, n=6). The linear range of loganin was within 0.009-2.170 μg (r =0.999 9), and the average recovery was 103.59% (RSD =1.10%, n =6). Conclusion: The method is accurate, simple and feasible with good repeatability, which can be used for the quality control of Corni Fructus in the prepa-ration.
