✦ Synopsis

During the course of biosynthetical study of usnic acid in lichens (l), we found that the ethereal extracts of Cladonla mitis Sandst. gave an unidentified yellow spot (Rf: 0.36) being accompanied by the spot of (+)usnic acid (Rf:0.20) on the thin layer chromatogram developed on Silica gel G
