摘要
目的对薄叶卷柏及其变异类型进行比较鉴定研究。方法分别采用形态学、解剖学方法研究两者的植物形态、药材性状及其显微特征;采用薄层色谱、近红外漫反射光谱比较两者的异同。结果薄叶卷柏及其变异类型在形态解剖上存在较小但稳定的差异;其茎的显微构造极为特殊(有气室、横桥、多体中柱等特征);两者薄层色谱与近红外二阶导数光谱也略有不同。结论研究结果为其药材资源的开发利用提供了鉴定依据;其变异类型宜作为薄叶卷柏的一个变种处理。
Abstract
OBJECTIVE To explore the identification of the Chinese herbal drug "Baoyejuanbai"(Selaginella delicatula and its variable type).METHODS Several methods(including morphology,histology,TLC and NIR) were used to determine the pharmacognostical characters. RESULTS The morphological and histological observations indicated that the variable type of Selaginella delicatula,owned small and stable differences.Some extremely special histological characters,such as air chambers,cross-bridge and polystele,were observed in their stem.The diversity of color depth of chromatogram spots between the two sorts of samples was obtained by TLC.Moreover,there were certain differences in second derivative near-infrared spectra of the two samples.CONCLUSION The results provide scientific basis for the identification of Selaginella delicatula and suggeste that the variable type should be treated as a variety.
