Abstract

Sterols were extracted from the lichens Lobaria pulmonaria, Lobaria scrobiculata and Usnea longissima with chloroform-methanol (2:1) (solvent-extractable fraction) followed by saponification of the residual lichen material to give a tightly-bound sterol fraction. The compounds were principally ergosterol, episterol, fecosterol and lichesterol with minor quantities of C17, C28 and C29 monoenes and dienes of the phytosterol type.
