ANALYSES OF THE VOLATILE OIL CONSTITUENTS OF LANDOLPHIA OWARIENSIS P. BEAUV

The volatile oil, obtained by hydrodistillation of the leaves of Landolphia owariensis P. Beauv using Clavenger type apparatus, was analysed for its constituents GC-MS method. The examined material contained 0.08%v/w of essential oil. A total of 34 compounds were identified in the essential oil, accounting for 92.93% of the oil composition. The main components of the essential oil were pentadecanal (13.63%), 1-dodecanol (6.32%), tetradecanol (5.83%), hexadecatrienal (5.62%), squalene (4.63%), β-ionone (3.25%), α- ionone (2.38%), supraene (3.01%), α-farnesene (3%), carophyllene oxide (2%) and -spathulenol (1.78%). This is the first report on the volatile constituents from the leaves of Landolphia owariensis.
