Abstract
Since the last major review of the chemistry of liehen substances by Huneck in 1971 (171) there has been an accelerating rate of development in this field. As with all areas of natural produet chemistry this impetus has been provided by more rapid and improved methods for detecting, isolating and purifying lichen metabolites and in the structural elucidation of these Compounds. The techniques of thin layer chromatography and high Performance liquid chromatography have provided rapid and efficient methods for the detection and purification of lichen substances and the development of 13C-n.m.r. spectroscopy and sophisticated techniques in 1H-n.m.r. spectroscopy have greatly aided structural studies.
