Keywords:
Zanthoxylum laetum, essential oil, National Park, Pu MatAbstract
The samples leaf, bark and fruit of Zanthoxylum laetum was collected from Pu Mat National Park in May 2013 was isolated by steam distillation to give oil yield 0.5%, 0.4 and 1.0%, respectively and analyzed by Capillary GC and GC/MS. Thirty two components have been identified accounting more than 95.9% of the oil from leaf. The major constituents of this oil
appeared to be limonene (31.2%), sabinene (21.5%), β - pinene (9.0%) and α - pinene (7.9%). Twenty two components were identified in stems, which presented about 95.0% of the total composition of the oil. The major constituents of the essential oil were sabinene (52.9%), α - pinene (12.2%), germacrene D (4.9%) and limonene (3.7%). In the essential oil of the fruits
identified forty three components which presented about 95.3% of the total. Geranyl acetate (30.4%), limonene (13.3%), sabinene (11.6%) and geraniol (8.3%) are major components of fruit.
