Eleven compounds isolated from the extract of the Central Asian lichens comprised eight new glycosides having murolic, protoconstipatic and allo-murolic acids, as the aglycones and a saccharide moiety linked at C-18 made up of one or two sugars (glucose and apiose or rhamnose or xylose or arabinose). The structures were elucidated by using extensive spectroscopic analysis (1D and 2D NMR, MS, IR, UV and CD) and chemical methods.
