62 compounds were identified in the essential oil (steam distillation) of quince fruit, trans-α-farnesene (31.3%), (+)-trans-marmelo lactone (10.3%) and (-)-cis-marmelo lactone (13.0%) were detected as the major components. The marmelo lactones own a sweet and strong aroma and seem to contribute considerable to the main aroma of quince fruit. Some of the furfural (3.4%) probably is derived from the decomposition of precursors such as pentose and ascorbic acid in the process of steam distillation.
