摘　　要：目的:对长清产3个品系栝楼果皮进行红外光谱研究。方法:采用红外光谱三级鉴定法对长清产3个品系栝楼果皮粉末进行分析。结果:三者的一维谱图和和二阶导数红外光谱整体上比较相似,但部分吸收峰的峰形、峰位和峰强具有一定的差异,二维红外相关光谱中自动峰的峰数和峰位,峰强均有明显的区别。结论:红外光谱三级鉴定法可以快速、准确地鉴别3个品系栝楼果皮。Objective：To study the peels among three strains of Trichosanthes kirilowii in changqing by IR spectra method.Method：The general infrared spectroscopy（FTIR）,secondary derivative spectroscopy and two dimensional correlation infrared spectroscopy（2D-IR） were used to analyze the powder of the three strains of T.kirilowii.Result：In the one-dimensional spectra and the secondary derivative,the three strains of T.kirilowii.had certain differences in shape,position and intensity of partial absorption peaksin 2D-IR spectra the three strains had obvious feature.Conclusion：The multi-steps infrared IR macro-fingerprint is a rapid and accurate method to identify three strains of T.kirilowii.
