VOLATILE OIL CONSTITUENTS OF THE LEAVES AND WOODS OF Cedrela odorata AND Dalbergia latifolia FROM SOUTH WEST NIGERIA

Abstract

The essential oils from the leaves and woods of Cedrela odorata and Dalbergia latifolia were obtained by hydrodistillation and characterized by Gas Chromatography-Mass Spectrometry (GC-MS) method. A total of 10, 39, 72, and 6 compounds representing 97.63%, 99.16%, 95.13% and 99.83% were identified in Cedrela odorata leaf, wood, Dalbergia latifolia leaf and wood respectively. The major components in Cedrela odorata leaf are -copaene (4.40%), -santalene (4.57%), cubenol (8.71%),elemene (23.06%) and (-)-spathulenol (42.49%) while the wood was dominated by -eudesmol (8.84%), z-nerolidol (9.23%), -bisabolol (10.95%), -curcumene (12.31%) and -cedrene (17.56%). The leaf essential oil of Dalbergia latifolia had in its composition majorly -bergamotene (4.23%), (-)-spathulenol (4.49%), -caryophyllene oxide (5.04%), -selinene (4.89%), 1-heptariacotanol (5.71%) and heptacosane (6.31%) while the wood contained mainly methylcyclohexane (4.93%), hexanal (6.43%), m-xylene (16.71%) and p-xylene (58.8%).
