Abstract: Objective To assay Icariine, Epimedin C, asperosaponin Ⅵ, psoralen and angelicin in Xianlinggubao capsules via multi-wavelength HPLC method. Methods Separation was carried out on Welch Ultimate® XB-C18 column. The mobile phase was acetonitrile-water system and a linear gradient elution was used. The column temperature was 30 ℃. The detection wavelength for Icariine, Epimedin C,asperosaponin Ⅵ was set at 212 nm, psoralen and angelicin at 246 nm. Results Five components reached baseline separation, the linearity was good when sample size was in the range of 0.008 2-0.328 μg for Icariine(r=0.999 5), 0.055 6-2.224 μg for Epimedin C (r=0.999 6), 0.144 1-5.764 μg for asperosaponin Ⅵ(r=0.999 6), 0.005 4-0.215 2 μg for psoralen(r=0.998 0), 0.006 6-0.265 6 μg for angelicin(r=0.998 5). The average recoveries were 97.59%, 98.58%, 98.11%, 97.86%, 98.22% respectively. The RSDs of recovery were all less than 2.0%. Conclusion This method is simple, accurate, with good separation, high sensitivity for the assay of multiple components in Xianlinggubao capsule.
