Abstract:
Objective To establish a joint wavelength switching HPLC gradient elution method for simultaneous determination of darutoside, kirenol, darutigenol, fangchinoline and d-tetrandrine in Xixian Fengshi Wan. Methods A Kromasil C18 column (4. 6 mm × 250 mm, 5 μm) was used with a mobile phase A; acetonitrile-methano (2: 1) and mobile phase B: 0. 05% acetic acid solution with gradient elution. The flow rate was 1. 0 mL/min; the injection volume was 20 μL; darutoside, kirenol and darutigenol were detected at 215 nm, and fangchinoline and d-tetrandrine were detected at 280 nm. Results In the given concentration range, the linearity ranges of darutoside, kirenol, darutigenol, fangchinoline and d-tetrandrine were 6. 45-129. 00 μg/mL (r=0. 999 5), 5. 61-112. 20 μg/mL (r=0. 999 9), 4. 25-85. 00 μg/mL (r=0. 999 3), 9. 19-183. 80 μg/mL (r =0.999 8), and 11. 05-221. 00 μg/mL (r=0. 999 7), respectively; and their average recoveries and RSD were 98. 73% (1. 43%), 97. 63% (1. 28%), 99. 44% (1. 29%), 98. 33% (1. 38%), and 97. 36% (1. 37%), respectively. Conclusion The established joint wavelength switching HPLC gradient elution method is simple, accurate and reproducible; it can simultaneously determine the contents of darutoside, kirenol, darutigenol, fangchinoline and d-tetrandrine in Xixian Fengshi Wnn and can be used for quality control of Xixinn Fengshi Wan.
