摘要:

本文采用傅里叶变换中红外光谱技术结合化学计量学方法对荒漠肉苁蓉进行了产地鉴别研究。通过中红外光谱技术对新疆、内蒙古、青海和哈萨克斯坦四个产地的荒漠肉苁蓉进行了中红外光谱测定,获得荒漠肉苁蓉的中红外光谱特征;通过谱峰归属发现,荒漠肉苁蓉中含有苯乙醇苷、黄酮类和糖苷类等成分;相似度评价方法能够对内蒙古和哈萨克斯坦样品有较好的区分效果;通过双指标序列(共有峰率和变异峰率)分析发现,产地对荒漠肉苁蓉的品质有一定的影响;主成分分析能够将不同产地的样品聚为相对独立的类群,实现了荒漠肉苁蓉的产地鉴别需求。

Abstract:

In this paper,Fourier transform mid-infrared spectroscopy and chemometric methods were used to identify the origin of Cistanche deserticola.The mid-infrared spectroscopy of the C. deserticola from Xinjiang,Inner Mongolia,Qinghai and Kazakhstan was carried out by mid-infrared spectroscopy technology,and the characteristics of the C. deserticola were obtained.Through the assignment of spectral peaks,it was found that the C. deserticola contained phenethanol glycosides,flavonoids and glycosides.The similarity evaluation method could distinguish the samples from Inner Mongolia and Kazakhstan.Through the analysis of double index sequence (shared peak rate and variable peak rate),it was found that the production area had a certain influence on the quality of C. deserticola.Component analysis could group samples from different producing areas into relatively independent groups,fulfilling the demand for identification of the origin of C. deserticola.

Key words: Cistanche deserticola, different producing areas, mid-infrared spectrum, dual index sequence, principal component analysis
