几种花粉的傅里叶变换红外光谱研究

Fourier Transform Infrared Spectroscopic Study of Pollen

本文利用傅里叶变换红外光谱技术(FTIR)对7种植物[玉兰、香水百合、天竺葵(粉红,红色)、兰花、菊花、马蹄莲]花粉进行了研究。结果显示,花粉样品的红外光谱主要由蛋白质、多糖、脂类物质的特征吸收峰组成。不同种花粉的红外光谱的差异表现为脂类物质的特征吸收峰强度的变化,多糖特征吸收峰峰形的区别,以及蛋白质和多糖的特征峰强度比的不同。不同颜色的天竺葵光谱差异较小,仅脂类特征吸收峰略有差异。研究表明,利用红外光谱建立数据库,有可能依据花粉的傅里叶变换红外光谱鉴别植物。

Fourier transform infrared （FTIR） spectroscopy was used to study the pollen samples of seven different plant species belonging to six different genus. The infrared spectra of pollen are mainly composed of the absorption bands of protein,polysaccharide and lipids. Remarkable differences are observed in the spectra of different genus, comparatively small,differences are observed in the spectra of different color geranium. The results offer a useful information for a further study of pollen. The FTIR method, using spectra as a data bank, might classify and identify pollen and plant species belonging to the different genus.
