Objective:To develop an HPLC method to determine isorhamnetin-3-O-neohesperidoside in intermediate products of Hongtengfang.Methods: The separation was performed on an ACE C18(4.6 mm×250 mm
5 μm)column with acetonitrile-water-acetic acid(14∶79.4∶0.6)as the mobile phase.The flow rate was 1.0 mL·min-1
the wavelength of UV detector was set at 254 nm and the column temperature was set at 20 ℃.Results: The linear relationship of Isorhamnetin-3-O-neohesperidoside was in the range of(0.040 4) μg~2.02 μg(r=(0.999 95)).The average recovery of isorhamnetin-3-o-neohesperidoside was 99.78%(n=6)
