The volatile constituents of five fruits from four Syzygium species from Malaysia were isolated by vacuum distillation with subsequent extraction of the distillates with dichloromethane. The concentrated extracts were analysed by capillary GC and GC-MS. Forty-three components were identified in rose

✦ Synopsis
The volatile constituents of the fruits of Annona glabra L. growing wild in North Brazil were analysed by GC±MS. The fruits were collected at three stages of ripening: unripe, half-ripe and ripe. The most abundant class of compounds found in the aromas were terpenoids. The major components identi®ed were a-pinene (unripe, 18.5%; half-ripe, 11.3%; ripe, 15.0%), limonene (unripe, 20.0%; half-ripe, 20.7%; ripe, 20.6%), a-phellandrene (unripe, 21.0%; half-ripe, 1.2%; ripe, 2.0%) and (E)-b-ocimene (unripe, 15.8%; halfripe, 19.7%; ripe, 18.3%).
