Abstract:In this article, the chemical compositions of 14 kinds of fungus-growing materials, and their corresponding rhizomorph and G. elata are analysed with thin layer chromatography. The properties of each G. elata and the contents of gastrodin in each G. elata are also analysed. The result shows that their properties and chemical compositions are similar, thus providing a basis for a larger choice of fungus-growing materials in cultivating G. elata.
