Chemical Compositions of Essential Oil of Agarwood <i>(Aquilaria crassna)</i> Harvested in Phu Quoc Island, Vietnam

Abstract

The importance of natural products derived from Agarwood species is increasingly emphasized in the production of perfumery or cosmetic products made on Agarwood species. On the other hand, due to the predominant amount of aromatic compounds in essential oils, frankincense essential oil is increasingly popular with high economic value. Therefore, in this study, we focused on the extraction process of essential oils and evaluated the chemical composition present in the essential oils by the GC-MS method. Differences in the composition of essential oils between natural and artificial agarwood may be due to species, habitat conditions, climate, geographical conditions, and extraction methods in different regions. Specifically, volatile components in essential oils were identified as Neopetasone (14.43%); Dihydroagarofuran-15-al (9.20%); Jinko-cramol (5.02%); Valeriano (4.94%); Agarofuran <b-> (8.02%); Dihydrokaranone (3.25%), Valenca-1 (10), 8-dien-11-ol (5.95%) and Selina-4,11-dien-14-al (2.73%), contribute to determining the main aroma in Agarwood essential oil.
