Abstract:Objective To HPLC method was established for the determination of Oleanolic acid and ursolic acid in Micromeria biflora Benth. Methods The contents of Oleanolic acid and Ursolic acid in Micromeria biflora Benth were determined by HPLC,The chromatographic column is Thermo Acclaim C18(250 mm×4.6 mm,5 μm),The mobile phase was methanol-water-Glacial acetic acid-Triethylamine(85∶15∶0.03∶0.06),The UV detection wavelength was 210 nm,The flow rate was 0.8 mL/min,The column temperature was 15℃. Results There was a goog linear relationship between the volume of oleanolic acid and ursolic acid in the range of 0.20~2.46 μg(R=0.9997) and 0.49~6.15 μg(R=0.9999),The RSDs of precision,stability,repeatability tests were less than 2%,The average recoveries were 98.4%(RSD=2.3%) and 98.3 %(RSD=2.7%).Conclusion A method for simultaneous determination of oleanolic acid and ursolic acid in Micromeria biflora Benth,The results are accurate and reliable, with good separation, high sensitivity, high accuracy and simple preparation,It can provide a good method and basis for quality evaluation and standard promotion of Micromeria biflora Benth.

姜味草为唇形科植物姜味草Micromeria biflora Benth.的干燥全草,别名地生姜、小姜草、小香草,味苦,辛,性温,具有温中散寒、理气止痛的功效[1-3],分布于贵州、云南、西藏等地[4],是云南常用草药。已有报道通过水蒸气蒸馏法和超临界CO2提取姜味草中的挥发油,并采用CG-MS联用法对其化学成分进行分析[5];采用气相色谱法对姜味草挥发油中橙花醛与香叶醛的含量进行测定[6];采用薄层色谱扫描法对云南不同产地姜味草中齐敦果酸的含量进行测定[7];采用高效液相色谱法对姜味草中非挥发性成分齐敦果酸和熊果酸的含量进行测定[8]。齐墩果酸和熊果酸具有抗氧化、抗癌、降血脂、降血糖和保肝等功效[9-12]。通过实验建立高效液相色谱法测定姜味草中齐墩果酸和熊果酸含量的方法,为姜味草的质量控制提供依据。
