【摘要】 目的 :用高效液相色谱法测定风湿液中蛇床子素的含量。方法 :固定相为ODS柱 ,流动相为甲醇 0 1mol·L 1硫酸铵水溶液 ( 6 5∶37) ,用硫酸溶液 ( 1→ 5 )调节 pH为 2 5 0 ;检测波长为 32 2nm。 结果 :回收率为 10 1 1% ,RSD为 3 0 %。结论 :该法能使干扰峰与蛇床子素峰完全分离更多还原

【Abstract】 OBJECTIVE:HPLC was used to determinate osthol in Fengshi Oral Liquid METHODS:ODS column as stationary phase, CH 3OH01mol·L 1 (NH 4) 2SO 4 (65∶37),adjust pH to 250 by sulphuric acid solution (1→5) as mobile phase,322 nm as detective wavelength RESULTS: The recovery of osthol was 10110%, and RSD was 30% CONCLUSION: The peaks of osthol and interference were separated completely更多还原
