薄层色谱法鉴别化合物的标准方法使用三种溶剂系统和穿孔卡片上编码的RF类别。这种方法已被改进和扩展到包括易于制备的水解和O-甲基化产物，并应用于地衣真菌次生产物的研究。报告的数据允许确认许多物质以前难以确定和建议的结构，某些类型的新化合物提取的植物标本的碎片。本文给出了220种化合物及其衍生物在三种标准溶剂体系中的新数据。
A standardized method for the identification of compounds by thin layer chromatography uses three solvent systems andRFclasses coded on punched cards. This method, applied to the study of secondary products of lichen-forming fungi, has been imporoved and expanded to include easily prepared hydrolysis and O-methylation products. The data reported allow the confirmation of many substances previously difficult to identify and the proposal of structures for certain types of new compounds extrated from fragments of herbarium specimens. New data are given for 220 compounds and derivatives chromatographed in three standard solvent systems.
