摘要
目的:分析不同产地白花蛇舌草中齐墩果酸的含量,为药材及其制剂的质量控制提供参考.方法:采用高效液相色谱法测定,色谱柱:Waters C18柱(250mm×4.6mm,5μm);流动相:甲醇-水-冰乙酸-三乙胺(90∶ 10∶0.03∶ 0.06);检测波长:210nm;柱温:20℃;流速:0.6mL/min;进样量:20μL.结果:齐墩果酸在10.1~202.0μg/mL(r=0.9998)范围内线性关系良好;平均回收率为98.4%,RSD为0.6%.结论:本方法准确、重现性好,可应用于药材及其制剂的质量控制.
Objective:To determine the oleanolic acid in Hedyotis Diffusa Willd from different sources and to provide a reference for quality control of raw materials and preparations. Methods:The analysis was performed by HPLC with C18 column. The mobile phase was consisted of methanol - water - glacial acetic acid - triethylamine(90: 10: 0. 03: 0.06) with detection wavelength at 210 nm. The flow rate was 0.60 mL/min and the column temperature was maintained at 20℃. Results: The linear range of oleanolic acid were 10.1 - 202.0μg/mL(r = 0. 9998) respectively. The average recovery of oleanolic acid were 98.4%, with RSD being 0.6% respectively. Conclusion: The method developed in this study appeared accurate, convenient and reproducible and can be used for quality control of oleanolic acid raw materials or preparations of Hedyotis Diffusa Willd.
