摘　　要：利用红外光谱对新疆4个现有昆仑雪菊产区的雪菊花序进行分析研究。结果表明4个产地雪菊所含主体成分相近,其红外光谱在1735-1515 cm-1和1070 cm-1都有较强吸收峰,但不同样品在1735 cm-1,1636 cm-1和1517 cm-1附近峰形、峰强度存在一定差异,说明各产地雪菊所含油脂与黄酮类等成分相对含量不同。利用红外光谱分析鉴定不同产地昆仑雪菊药材,方法快速、简便,能够直接反映生长环境对雪菊化学成分的影响。Fourier Transform Infrared spectroscopy was applied to analyze identify the Kunlun chrysanthemum from 4 different county of Xinjiang They all had strong absorption peaks in the range of 1735-1515 cm-1.However,peaks around 1735 cm-1,1636 cm-1 and 1517 cm-1 have varied peak shape and intensity,suggesting they contained different amount of flavonoids and lipids.Consequently,it was demonstrated that infrared spectroscopy can be used to rapid discriminate Kunlun chrysanthemum daisy herbs from different regions and subsequently to reflect the influence on their chemical constituents by growing environment.
