Terpenoids from Dacrycarpus imbricatus.

The phytochemical investigation of the hexane extract from the twigs and leaves of Dacrycarpus imbricatus (Blume) de Laub led to the isolation of a rare sesquiterpene, spathulenol ( 1 ) along with three diterpenes named pimaric acid ( 2 ), trans -communic acid ( 3 ) and cis -communic acid ( 4 ). Their structures were determined by combination of spectral analysis and comparison with reported data. This is the first report on isolation of compound 1 from the Podocarpaceae family. Keywords. Dacrycarpus imbricatus , spathulenol, pimaric acid, communic acid.
