摘要: 建立柿叶中白桦脂酸、齐墩果酸和熊果酸的反相高效液相色谱(RP-HPLC)分析方法。色谱条件为Thermo C18色谱柱(250 mm×4.6 mm,5 μm);流动相:乙腈:磷酸水溶液(pH=3.0)=85:15;流速:0.8 mL/min;检测波长:209 nm;柱温:30 ℃。白桦脂酸进样量在0.124~3.100 μg范围内线性关系良好,r=0.9996,平均加样回收率为98.22%;齐墩果酸进样量在0.160~4.000 μg范围内线性关系良好,r=0.9994,平均加样回收率为95.23%;熊果酸进样量在0.288~7.200 μg范围内线性关系良好,r=0.9998,平均加样回收率为103.87%。磨盘柿叶中白桦脂酸、齐墩果酸和熊果酸含量为0.872、1.406和4.598 mg/g。本法可作为柿叶中白桦脂酸、齐墩果酸和熊果酸含量的测定方法。

Abstract: A RP-HPLC method was established for the simultaneous determination of betulinic acid,oleanolic acid and ursolic acid in persimmon leaves.Thermo C18 column (250 mm × 4.6 mm,5 μm)was used for the chromatographic separation,acetonitrile-phosphoric acid aqueous solution(pH=3.0)(85:15)was used as the mobile phase with a flow rate of 0.8 mL/min.The detection wave length was 209 nm and the temperature of the column was 30 ℃.The linear ranges for betulinic acid,oleanolic acid and ursolic acid were 0.124-3.100 μg(r=0.9996),0.160-4.000 μg(r=0.9994)and 0.288-7.200 μg(r=0.9998),respectively.The average recoveries of the developed HPLC method were 98.22% for betulinic acid,95.23% for oleanolic acid and 103.87% for ursolic acid.The content of betulinic acid,oleanolic acid and ursolic acid in the leave of MoPan were 0.872,1.406 and 4.598 mg/g,respectively.The developed method can be used to simultaneously determine the content of betulinic acid,oleanolic acid and ursolic acid in persimmon leaves.
