Objective: To develop an HPLC method for detecting icariin in Yanzong Yuzi capsules. Method: An Appollo C18 column (4.6 mm×250 mm
5 μm) was used. The mobile phase consisted of acetonitrile-water (26: 74). The detection wave length was set at 270 nm and the column temperature was at room temperature. Result: Icariin showed a good linear relationship in the range of 0.025 5 to 0.408 μg
r=0.999 8.The recovery and RSD were 99.4% and 1.25%(n=6). Conclusion: Method was proved to be simple
accurate and repeatable to determine the content of icariin in Yanzong Yuzi capsules.
