Objective: To establish the method for content determination of Yigangao. Method: HPLC was used to determine the content of icariin. Result: The spots were clear on TLC
and icariin was linear in the range of 0.020 06-0.802 4μg. The average recovery was 100.25%
with RSD of 1.4%. Conclusion: The method established is simple and feasible with good reproducibility.
