目的建立山楂中熊果酸和齐墩果酸含量测定方法。方法色谱柱Agilent XDB-C18柱(250 mm×4.6 mm,5μm),流动相甲醇-水(85:15),流速1~20 min 1.0 ml/min,20~35 min 0.5 ml/min,检测波长210 nm,柱温30℃。结果齐墩果酸进样量在0.4076~8.152 ug范围内与峰面积线性关系良好;熊果酸进样量在0.2706~5.412 ug范围内与峰面积线性关系良好。结论本方法操作简便准确,可作为山楂的质量控制参考。
Objective To establish a method for the determination of ursolic acid and oleanolic acid in hawthorn. Methods The column was Agilent XDB-C18 (250 mm × 4.6 mm, 5 μm). The mobile phase consisted of methanol-water (85:15), flow rate of 1 to 20 min, 1.0 ml / min and 20 to 35 min, 210 nm, column temperature 30 ℃. Results The oleanolic acid injection showed a good linear relationship with the peak area in the range of 0.4076 ~ 8.152 ug. The injection volume of ursolic acid had a good linear relationship with the peak area in the range of 0.2706 ~ 5.412 ug. Conclusion The method is simple and accurate, and can be used as a quality control reference for hawthorn.
