Abstract

Objective:To establish the quality standard for Naolingsu Tablets.Methods: Applying the technique of TLC, Radix Ginseng and Herba Epimedii were identified. The content of icariin was determined by HPLC. Results: Radix Ginseng and Herba Epimedii can be determined by TLC. Icariin showed a good linear relationship in the range of 0.011 ～ 0.424 μg and the average recovery is 102.1% , RSD is 1.0% . Conclusion: The methods are simple, sensitive and accurate with good reproducibility. The methods may be used for quality control of Naolingsu Tablets.
