近红外漫反射光谱法在川续断属植物鉴别中的应用

摘要

A new method for identification of Dipsacus asperoides C. Y. Cheng et T. M. Ai from Dipsacus Plant Taxonomy by near infrared reflectance spectroscopy is put forward. The PLSDA model established on the MSC and SD spectraes is used to identify Dipsacus asperoides C. Y. Cheng et T. M. Ai from Dipsacus atropurpureus C. Y. Cheng et T. M. Ai, Dipsacus japonicus Miq. , Dipsacus daliensis T. M. Ai, Dipsacus enshiensis C. Y. Cheng et T. M. Ai, Dipsacus fulingensis C. Y. Cheng et T. M. Ai. Results The method can identify Dipsacus asperoides C. Y. Cheng et T. M. Ai from Dipsacus Plant Taxonomy. This method is rapid, accurate and simple; it can be used in the identification of Dipsacus asperoides C. Y. Cheng et T. M. Ai.%用近红外漫反射光谱法对川续断和部分川续断属其它植物进行鉴别,为川续断的品种鉴别和质量评价提供一种新的可能的方法和手段.分别对6种川续断属植物的近红外漫反射原始图谱和经过多元散射校正(MSC)和二阶导数(SD)处理后的图谱建立PLSDA模型.快速、准确地鉴别川续断和部分川续断属其它植物,同时不同产地的同种样品也得到了准确的区分.本方法快速.准确,不破坏样品,能用于鉴别川续断和川续断属其它植物.
