Determination of acteoside isomer in Total Cistanches Glycosides Capsules by HPLC / 中成药

Objective:To establish a determination of acteoside isomer in Total Cistanchis Glycosides Capsules by HPLC.Methods: HPLC analysis was carried out on C 18 ODS column with acetonitrile——1.5% acetic acid as the mobile phase. The linear gradient of acetonitrile was from 11.5% to 20%(0-25min). The detection wavelength was 335nm. Results: The method was linear in the range of 0.2～1.0?g, r =0.9996. The average recovery was 98.85%, RSD was 1.51%( n =9). Conclusion:This method is simple, accurate, highly sensitive and reproducible. It may be used for the determination of acteoside isomer in Total Cistanchis Glycosides Capsules.
