LI Yan, FU Xin-tong. Study on Quality Standard of Yigangao[J]. Chinese journal of experimental traditional medical formulae, 2012, 18(18): 115-117. DOI: 10.13422/j.cnki.syfjx.2012.18.047.
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.
