Chemical composition of essential oil of exudates of Dryobalanops aromatica
Abstract
Purpose: To identify the chemical composition of essential oil from the exudates of Dryobalanops aromatica from Malaysia.
Methods: Exudate was collected from D. aromatica and subjected to fractional distillation to obtain essential oil. Gas chromatography-mass spectrometry (GC-MS) was used to characterize the composition of the isolated essential oil.
Results: The yield of essential oil was 7.58 %, with the highest yield (3.24 %) within the first 2 h of fractional distillation. Thirty compounds which accounted for 97.56 % of essential oil composition were identified. These include sesquiterpenes (46.87 %), monoterpenes (31.05 %), oxygenated monoterpenes (16.76 %) and oxygenated sesquiterpenes (2.13 %). Borneol accounted for 0.74 % of the essential oil.
Conclusion: Essential oil from the exudates of D. aromatica contains terpenoid compounds and borneol.
