摘要
目的:对来源于胡颓子属的3种药用植物(胡颓子、披针叶胡颓子、宜昌胡颓子)叶进行红外光谱鉴别研究。方法:采用傅里叶变换红外光谱及二阶导数红外光谱法研究比较3种植物叶粉末的红外谱图特征。结果:3种植物叶的红外光谱、二阶导数红外光谱整体上虽较相似,但某些吸收峰的峰强度或峰强比有一定差异,其中二阶导数光谱的差异更为明显;披针叶胡颓子大叶类型与小叶类型样品的红外光谱图差异极小;不同采收期同种植物叶样品的种内差异远小于同属不同种之间的种间差异。结论:红外光谱法能较可靠地辅助用于胡颓子属3种药用植物叶的鉴别。
Objective： To study and identify the three species of dry medicinal plant leaves from Elaeagnus genus（E. pungens,E. lanceolata and E. henryi） by Infrared Spectroscopy（IR）. Methods： Fourier transform infrared spectroscopy and second derivative infrared spectroscopy were used to study and compare the characteristics of leaves of three Elaeagnus medicinal plants. Results： The IR spectra and second derivative infrared spectra of the three Elaeagnus plants leaves were similar on the whole,the intensity or ratio of intensity of some absorption peaks still had certain distinctions,and the differences of the second derivative infrared spectra were more obvious. There were only slight differences between large and small leaf type of samples of Elaeagnus lanceolata; the differences of the plant leaves of one species collected in different harvest periods were far smaller than those of others belonging to the same genus. Conclusion： IR can be relatively reliably used for identification of the three Elaeagnus leaves.
