Abstract

The volatile constituents of the fruits of Lansium domesticum Correa (duku and langsat) and Baccaurea motleyana (Muell. Arg.) Muell. Arg. (rambai) were isolated by vacuum distillation with subsequent extraction of the distillates with dichloromethane. The concentrated extracts were analysed by capillary GC and GC-MS. The volatile constituents of both duku and langsat fruits were dominated by sesquiterpene hydrocarbons, the most abundant of which was germacrene-D. (E)-Hex-2-enal was the major component of rambai fruit volatiles which also contained high levels of methyl 2-hydroxy-3-methylbutanoate, methyl 2-hydroxy-3-methylpentanoate and methyl 2-hydroxy-4-methylpentanoate.
