目的 建立高效液相色谱(HPLC)法同时测定柴葛解酒颗粒中 6 种有效成分(葛根素、二氢杨梅素、鸢尾苷、葛花苷、槲皮素、柴胡皂苷 A)的含量,为其质量标准的完善提供参考。方法 采用 Agilent 5 HC- C18色谱柱(4.6 mm × 250 mm,5 μm);以 0.2% 磷酸水(A)-乙腈(B)为流动相,梯度洗脱;流速:1.0 mL•min-1 ;柱温:30 ℃;检测波长:210 nm;进样量:10 μL。结果 在上述色谱条件下,柴葛解酒颗粒中葛根素、二氢杨梅素、鸢尾苷、葛花苷、槲皮素、柴胡皂苷 A 可实现较好的分离,其线性范围分别为 21.16 ~ 677.00 μg•mL-1 (r = 1.000 0)、11.16 ~ 357.00 μg•mL- 1(r = 0.999 7)、19.28 ~ 617.00 μg•mL- 1(r = 0.999 9)、10.38 ~ 332.00 μg•mL-1 (r = 0.999 9)、15.38 ~ 492.00 μg•mL- 1(r = 0.999 8)、15.50 ~ 496.00 μg•mL- 1(r = 0.999 6),各成分均有良好的线性关系;平均加样回收率在 98.43% ~ 101.35% 之间,RSD 均小于 3%。结论 所建立的方法能同时测定柴葛解酒颗粒中葛根素、二氢杨梅素、鸢尾苷、葛花苷、槲皮素、柴胡皂苷 A 的含量。该方法准确、重复性好、可操作性强,可为柴葛解酒颗粒的质量评价与控制提供依据。

Objective HPLC method was established to simultaneously determine the content of six active components including puerarin,dihydromyricetin,tectoridin,kakkalide,quercetin,and saikosaponin A in Chaige Hangover-alleviating Granules (CAG),and to provide a reference for the improvement of its quality standard. Methods The separation was performed on an Agilent 5HC-C18column (4.6 mm × 250 mm,5 μm) with 0.2% phosphoric acid in water (A)-acetonitrile (B) as the mobile phase in a gradient elution at a flow rate of 1.0 mL•min-1 . The column temperature was 30 ℃,the detection wavelength was 210 nm,and the injection volume was 10 μL. Results A good separation of puerarin,dihydromyricetin,tectoridin,kakkalide,quercetin,and saikosaponin A in CAG could be achieved under the above chromatographic conditions,with the linear ranges of 21.16 ~ 677.00 μg•mL-1 (r = 1.000 0),11.16 ~ 357.00 μg•mL-1(r = 0.999 7),19.28 ~ 617.00 μg•mL-1(r = 0.999 9),10.38 ~ 332.00 μg•mL-1(r = 0.999 9), 15.38 ~ 492.00 μg•mL-1 (r = 0.999 8),and 15.50 ~ 496.00 μg•mL-1 (r = 0.999 6) respectively,showing a good linear correlation. The average recoveries ranged from 98.43% ~ 101.35%, and the RSDs were all less than 3%. Conclusion The method can simultaneously determine the content of puerarin, dihydromyricetin, tectoridin, kakkalide,quercetin,and saikosaponin A in the CAG. Moreover,the established method is accurate,reproducible and operable,which provides the basis for the quality evaluation and control of CAG.
