| Summary: | For many years, most researches involving agarwood mainly focused on extracting the agarwood
oil from the infiltrated resin, the most sought non-timber forest product from Aquilaria species which
has high demand and prices. This led to other parts of this valuable plant species being considered as
waste. Thisinclude the agarwood hydrosol (byproduct produced during the water distillation). Hydrosol
has been reported to retain certain aromaticsof its primary essential oil. Therefore, the present study is
conducted to identify the composition of the agarwood hydrosol extractsfromAquilaria species by using
gas chromatography-mass spectrometry (GCMS). From the analysis, there were a total of 46, 48, 40,
53, 58 and 62 compounds detected in hydrosol extract samples of 1, 2, 3, 4, 5 and 6 respectively.
Accordingly, the oxygenated and phenolic compounds were found to be present in all hydrosol extract
samples. The detected phenolic compounds include Phenol, 2,5-bis (1,1-dimethylethyl)-,.Phenol, 2,4-
bis (1,1-dimethylethyl)- and 9-Octadecenoic acid (Z)-, methyl ester. These compounds are believed to
possess various potential biological activities including antioxidant activities. Sample 1 and 2
consistsesquiterpene compounds such as (-)- Aristolene, Naphthalene, decahydro-4a-methyl-1-
methylene-7-(1-methylethylidene)-,(4aR- trans)-,Azulene,1,2,3,3a,4,5,6,7-octahydro-1,4-dimethyl-7-
(1-methylethenyl)-,[1R- (1.alpha.,3a.beta.,4.alpha.,7.beta.)]- andalloaromadendrene where the later has
the highest number of oxygenated and antioxidant compounds. To this end, it is noteworthy that findings
from this study have unravel the potential medicinal benefits of agarwood hydrosol and thus realizing
the waste to wealth paradigm. |
