目的:建立同时测量六味补血颗粒中主药有效成分芍药苷和阿魏酸含量的方法。方法:采用Symmetry C18色谱柱(4.6×250 mm,5μm);流动相采用甲醇-0.2%磷酸溶液梯度洗脱;流速1.0 mL/min;检测波长为285 nm;柱温:25℃。结果:芍药苷在17.44~174.4μg.mL-1的范围内峰面积积分值与浓度呈良好的线性关系(r=0.9997),平均回收率为98.9%,RSD=1.29%(n=6);阿魏酸在0.356~14.24μg.mL-1的范围内峰面积积分值与浓度呈良好的线性关系(r=0.9999),平均回收率为98.68%,RSD=2.4%(n=6)。结论:该法准确、简便,重现性好,可作为六味补血颗粒制剂质量控制的有效方法。
Objective: To establish a method for simultaneous determination of paeoniflorin and ferulic acid in the active ingredient of Liuwei Buxue Granules. Methods: Symmetry C18 column (4.6×250 mm, 5 μm) was used; mobile phase was eluted with methanol-0.2% phosphoric acid gradient; flow rate was 1.0 mL/min; detection wavelength was 285 nm; column temperature was 25°C. Results: The peak area integral and concentration of paeoniflorin in the range of 17.44~174.4μg.mL-1 showed a good linear relationship (r=0.9997). The average recovery was 98.9% and RSD was 1.29% (n=6). There was a good linear relationship between peak area integral and concentration of ferulic acid in the range of 0.356~14.24μg.mL-1 (r=0.9999). The average recovery was 98.68% and RSD was 2.4% (n=6). Conclusion: The method is accurate, simple, and reproducible. It can be used as an effective method for quality control of Liuwei Buxue Granules.
