Abstract

This is the first report on the GC-MS profile of the ether-soluble fraction (ESF) of the methanol extract of the lichen Ramalina capitata (Ach.) Nyl . ( Ramalinaceae ). The profile was dominated by orcinol (22.9 %) and its monomethyl ether (30.9 %), which accounted for more than a half of the GC-MS analyzable fraction of ESF. Significantly lower amounts of structurally related sparassol (5.8%) and atraric acid (0.9 %) were also detected. Additionally, ESF contained methyl linoleate, methyl linolenate and methyl palmitate (17.3 %, 7.3 % and 5.0 %, respectively). GC-MS ANALIZA EKSTRAKTA LISAJA RAMALINA CAPITATA (ACH.) NYL.
