摘　　要：利用傅里叶红外光谱（FTIR）技术结合化学计量学分析方法来鉴别不同品种的月季花。不同品种月季花瓣的红外光谱整体上大致相似，主要由酚类、脂类、黄酮苷类及多糖类化合物的振动吸收组成。月季花二阶导数光谱在1800～700cm。区域有较大差异，选取1800～700cm。区域内的二阶导数光谱作为主要研究区域，利用SPSS软件对光谱进行相关分析、主成分分析及系统聚类分析。结果表明在主成分图中所有月季花瓣样本正确分类，分类准确率为100％，在系统聚类分析图中所有月季花样品都正确聚类。结果表明，FTIR技术结合化学计量学分析方法可以作为鉴别月季花花瓣的方法。Fourier transform infrared spectroscopy （FTIR） technology combined with chemometric analysis is applied to identify different varieties of Chinese roses. The infrared spectra of Chinese rose samples are similar on the whole, which are mainly composed of vibration absorption bands such as phenolic, lipid, glycosides, flavonoids, polysaccharides. The second derivative spectra of Chinese rose samples are different in the range of 1800-700 cm-1, the second derivative spectra in the range of 1800-700 cm-1 are selected to perform correlation analysis, principal component analysis （PCA） and hierarchical cluster analysis （HCA）. The PCA and HCA results show that all Chinese rose samples are classified correctly. It is demonstrated that FTIR technology combined with chemometric analysis method can be as a possible method for identifying different Chinese rose varieties.
