Tri terpenes from oakmoss evernia prunastri part 5


, : Tri terpenes from oakmoss evernia prunastri part 5. Helvetica Chimica Acta 62(3): 807-810

Seven triterpenoids were isolated from oakmoss (E. prunastri) extracts by column chromatography and identified as friedelin, taraxerol, 29-nor-21.alpha.-hopan-3,22-dione, moretenone, ursolic acid, lupeol and lanosterol.
