Chemical constituents of the essential oils of Goniothalamus uvariodes King

The leaf, bark and root oils of Goniothalamus uvariodes King were investigated by capillary GC and GC–MS. The leaf oil was made up mainly of sesquiterpenoids, with β ‐cubebene (15.2%) as the dominant component. The other major components were elemol (9.7%), epi ‐ α ‐cadinol (6.2%), α ‐muurolene (4.8%) and viridiorol (4.8%). The bark oil was also rich in sesquiterpenoids, with β ‐eudesmol (31.5%), γ ‐eudesmol (16.0%), hedycaryol (13.6%), α ‐eudesmol (5.6%) and ( Z )‐nerolidol (5.2%) as the major constituents. However, the major group of compounds in the root oil was monoterpenoids, of which terpinen‐4‐ol (39.5%) and 1,8‐cineole (14.0%) were the main representatives. Copyright © 2003 John Wiley & Sons, Ltd.
