GC-MS Analysis of Fragrance Constituents from Offcuts of Eaglewood and Chinese Eaglewood in Guangdong

Abstract:

Fragrance constituents in essential oils from the off-cuts of Eaglewood (A) and Chinese Eaglewood (B) in Guangdong have been analysed by GC-MS. Essential oil A was extracted by microwave additional extraction method, and oil B was provided by a flavors company. SPME-GC-MS analyses revealed that two oils possessed 29 same compounds, and their main fragrance compositions were sesquiterpene accounting for 94.99% and 94.19% of total essential oils, respectively. However, oil A exhibited 61 volatile compounds with agarospiro (17.32%), guaiac acetate (15.99%), guaiol (15.53%) and beta-Ionon (13.61%) being the major constituents. Oil B had 59 ones, and the major constituent was spathulenol (56.45%). In the first 60 min, oil B showed 28 distinctive compounds. And in 78~91 min, oil A displayed 14 fragrance compositions, while, oil B showed 1. The results explained that two essential oils possessed similar scent. However, their aroma quality was very different. Oil A showed longer holding fragrance. However oil B exhibited richer top note. This study demonstrated that offcuts of Eaglewood would also be used to extract essential oil to provide new variety of material for perfume industry.
