摘　　要：采用傅里叶变换红外光谱仪的衰减全反射附件——OMNI采样器,对湖北咸宁所产的金桂、银桂、蒲城丹桂、硬叶丹桂、天香台阁四季桂、小叶四季桂等4个种群的6个不同品种的桂花（Osmanthus fragrans）进行了红外光谱对比分析.结果表明,6个桂花样品在1 731～1 022 cm-1区域的红外光谱吸收峰差异明显.应用衰减全反射红外光谱技术可对不同品种的桂花进行快速鉴别.OMNI sampler, the attenuated total reflection accessory of the Fourier transform infrared spectrometer（ATR-FTIR）, was used to collect the infrared spectra of six kinds of Osmanthus fragrans belonging to four different species including thun- bergii,latifolius,aurantiacus ＇Pucheng＇ ,aurantiacus ＇ Yingye＇ ,sempeUTorens ＇Tianxiangtaige＇ ,sempegqorens ＇Xiaoye＇ from Xianning city, Hubei province. Results showed that the absorption peaks of the infrared spectra for different samples in the area of 1 731-1 022 cm-l were quite different from each other. The ATR-FTIR technique could rapidly identify different kinds of O. fragrans.
