摘要(Abstract):

目的:建立近红外定性分析模型能够对何首乌真伪进行鉴别,同时区分何首乌与其炮制品制何首乌,可用于该药材快速筛查,加强药品监管效能。方法:采集30多份何首乌和制首乌样品以及其伪品白首乌、冀蓼、毛脉蓼的近红外光谱图,利用近红外光谱技术结合化学计量学方法建立何首乌定性判别模型和一致性检验模型,并尝试对不同产地何首乌进行聚类分析。结果:所建模型能够将何首乌与其伪品准确识别,同时能够区分何首乌与制何首乌。结论:近红外光谱法在何首乌药材鉴别、分类中得到实际应用,可作为鉴别该药材的初筛手段。
Objective: To establish a near-infrared qualitative analysis model to identify the authenticity of Polygonum multiflorum and distinguish processed products Polygoni Multiflori Radix. Method: The NIR spectra were peformed on over 30 batches of P. multiflorum and Polygoni Multiflori Radix samples and the adulterants Cynanchum bungei,Pteroxygonum giraldii,Polygonum cillinerve to establish the qualitative discriminant model and the conformity test model of Polygonum multiflorum,and cluster analysis was used to analyze the samples from different origins. Result: The model is able to identify correctly P. multiflorum with its counterfeit,and distinguish between P. multiflorum and Polygoni multiflori Radix. Conclusion: Near-infrared spectroscopy can be applied in the identification of P. multiflorum,which could be used to screen Chinese herbal medicine preliminarily.
