Objective:To establish a HPLC fingerprint of Semen Oroxyli.Methods:The analysis was carried out on a Lichrospher C18 column(250 mm×4.6 mm
5 μm) eluted with the mobile phase consisted of acetonitrile(A) and water(B) all containing 1% acetic acid in gradient mode.The gradient program was as follows:0~30 min
A changed from 10%~25%;(30~50)min
A changed from 25% to 55%;then the column keeped for 5 min.The flow rate was 1.0 mL·min-1.The wave length was 280 nm and temperature was 30 ℃.Result:The fingerpring of Semen Oroxyli was estabilished.Conclusion:The method is repeatable and can be used in quality control of Semen Oroxyli.
