摘要: 目的:建立高效液相色谱法测定南瓜粉中胡芦巴碱的方法。方法:甲醇超声波提取样品中的胡芦巴碱,色谱柱为Zorbax-NH2(4.6×150mm,5μm),流动相为乙腈-水(80:20,V:V),流速为1ml/min,检测波长为265nm。结果:胡芦巴碱浓度在5.01~101.4μg/ml内呈现良好的线性关系,相关系数r=0.9999(n=5);精密度实验RSD=0.31%(n=5);平均回收率为85.28%,RSD=4.4%(n=6);测定三个品系的30个样品中南瓜粉中胡芦巴碱的含量为0.1219~0.4836mg/g。结论:首次建立了高效液相色谱法测定南瓜中胡芦巴碱含量的方法,为南瓜功能性成分开发和遗传育种提供了理论依据。

Abstract: objective: To set up a method for determination trigonelline in pumpkin powder by HPLC. Method: Pumpkin powder sample was extracted with methanol ultrasonic, Zorbax-NH2(4.6×150 mm, 5μm) column was used with mobile phase as acetonitrile-water (80:20,V:V). The flow rate was 1ml/min and detection wavelength was set at UV 265 nm. Result: The calibration curve is linear in the range of 5.01~101.4μg/ml, with the correlation coefficient 0.9999(n=5); the RSD 0.31(n=5) in the precision test, the average recovery rate 85.26% and RSD 4.4%(n=6). The contents of trigonelline in the three kinds of thirty samples are 0.1219~0.4836 mg/g. Conclusion: The method can provide scientific indexes for developing the functional compo-nent and selecting breed of pumpkin.
