HRGC and HRGC-MS identifications of bound aroma compounds from the pulp and the peelings of lulu fruit (Solanum vestissimum D.) were achieved after isolation of extracts obtained by Amberlite XAD-2 adsorption and methanol elution followed by hydrolysis with commercial pectinase enzymes. Whereas the aglycons identified in the peelings mainly consisted of terpenoids, with enantiomerically pure (R)-(-)-linalool as the main constituent, aglycons exhibiting aromatic structures, in particular, benzoic acid and methyl benzoate, predominated in the pulp. After per-O-methylation of a fraction obtained from the glycosidic extract by rotation locular countercurrent chromatography (RLCCC), HRGC-MS revealed linalool beta-D-glucoside as the bound conjugate of linalool in the peelings.
