Description
Summary:A standardized method for the identification of compounds by thin layer chromatography uses three solvent systems and R F classes 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.
