摘要
目的:建立高效液相色谱测定野木瓜中齐墩果酸含量的方法。方法:采用Shim—packVP—ODS柱(250mm×4.6mm);流动相为乙腈-1.1%乙酸水(94:6);流速0.5mL/min;检测波长205nm;柱温为室温;洗脱方式为等度洗脱。结果:齐墩果酸获得良好分离,在0.03—0.15mg/ml范围内线性关系良好,回归方程为Y:3.81424×10^-8x-0.00240239,相关系数r=0.9994,平均加样回收率为100.68%。结论:该方法精密度高,重现性好,简单易行。通过以上方法,测得野木瓜中齐墩果酸平均含量为0.1055%。
To establish an HPLC method to determine the content of oleanolic acid in Stamtonia Chinensis. Method: Oleanolic acid was sperated on an Shim - pack VP - ODScolumn. The mobile phase was acetonitrile - 1. 1% acetic acid water. The flow rate was 0.5ml/min. UV detection wavelength was 205nm. Column temperature was the room temperature. Results : Oleanolic acid was separated well. The repressive equation is : y = 3. 81424 × 10 - 8x - 0. 00240239, r = 0.9994. The relationship of injection amounts and peak was linear in the range of 0.03 -0.15mg/ml and the recovery rate was 100. 68%. Conclusion: The method is simple and available,of accuracy and good reproducibility. By this method, the content of oleanolic acid from Stanuntonia Chinensis is 0. 1055%.
