GAS CHROMATOGRAPHY- MASS SPECTROMETRIC ANALYSIS OF THE ESSENTIAL OIL OF EAGLEWOOD (AQUILARIA AGALLOCHA ROXB)
Keywords:
GCMS, Eaglewood, Essential oilAbstract
Objective: The investigation was carried out to study the phytochemical constituents of agar oil of Aquilaria agallocha grown in Assam.
Methods: Fungal infected agar laden wooden chips grown in Assam were soaked in water for 6 to 7 days and grounded into smaller pieces and hydro distilled to obtain the oil. 2 µl of the oil sample diluted in methanol was used for GC/MS analysis to study the chemical constituents.
Results: GC-MS analysis of the oil has shown the presence of at least 35 different compounds, out of which 17 compoundswere identified. Three furanoids viz. 3 methyl-2-(2 methyl-2-butenyl)-furan; 2-isobuteyl-3 methyl furan and 3-methyl-2-(2-oxopropyl)furan were identified as the main aromatic components of the oil. Besides these some acids, ketones alcohol and aldehydes were also identified and reported here.
Conclusion: Variation in the quality of the oil has been observed depending upon geographical region on which the trees are grown, age of the plant and extent of disease lesions formed in the wood, which was evident by studying the phytochemical constituents of the oil.
