Oxygenated spiro-triterpenoids possibly related to arborenes in sediments of a tropical, freshwater lake
چکیده انگلیسی
Three novel 3-oxygenated CD spiro-triterpenoids were tentatively identified as 13,15-spiro-arbor-9(11)-en-3-one, 3β-methoxy-13,15-spiro-arbor-9(11)-ene and 13,15-spiro-arbor-9(11)-en-3β-ol in solvent extracts of sediments from Lake Valencia. Their proposed origin from higher plants is based on structural precursor/product relationships and characteristics of the age distributions since the latest Pleistocene.
