异穗卷柏的显微与近红外光谱鉴定研究

Studies on the Identification of Selaginella heterostachys by Microscopic Observation and Near Infrared Spectra

摘要: 对两种不同类型的异穗卷柏(Selaginella heterostachys Baker)药材的外观形态、孢子与茎的显微特征及近红外光谱特征进行了比较研究。结果表明:两类异穗卷柏的植株性状虽有明显不同,但其孢子形态、茎的解剖特征及近红外漫反射光谱特征一致。研究结果为异穗卷柏物种分类与药材鉴定提供了依据。

Abstract: To establish parameters for identification of the medicinal material of two types of Selaginella heterostachys,several methods,including the morphological,microscopic and near infrared spectroscopic ones,were used in this study.The two types of S.heterostachys differ obviously in the morphological characters,but there are few differences in the spore appearance,histological characters of the stems,and the near infrared spectra.The results provided basis for classification of the species and identification of the medicinal material.
