In the study on constituents present in woody material of Bursera graveolens, aroma components responsible for the characteristic spicy, sweet and balsamic odor were examined by gas chromatography/olfactometry (GC/O) and GC/MS. Compounds 1-4 were isolated from volatile oil obtained by ether extraction of Bursera graveolens wood chips and structural determination was conducted by spectroscopic analysis and synthesis as (6S ,7aS )-5,6,7,7a-tetrahydro-7a-hydroxy-3,6-dimethyl-2(4H )-benzofuranone 1, (6S)-5,6-dihydro-3,6-dimethyl-2(4H )-benzofuranone 2, (+)-mintlactone 3 and (-)-isomintlactone 4.
