Chemical Components of Agarwood (Aquilaria crassna) Essential Oils Grown in Various Regions of Asia

Abstract

This study presents a chemometric study on agarwood (Aquilaria crassna) essential oils extracted from selected agarwood samples grown in various regions of Asia. Adopting gas chromatography-mass spectrometry (GC-MS) technique, it was revealed that essential oils, produced by hydrodistillation,constitutes mainly volatile aromatic compounds. Several major components are shared in all samples including dihydro-agarofuran-15-al, jinkoeremol, 10-epi-γ-eudesmol, agarospirol, valerianol, n-hexadecanoic acid, neopetasane and dihydrokaranone. Despite differences in composition, extraction yield and detected constituents found in analyzed samples, characteristic aromatic compounds were abundantly found in the Agarwood essential oil. These discrepancies could be due to cultivation season, climatic conditions and extraction methods. Unambiguous identification of components in agarwood essential oils thereby opens new potential in the application of high-value aromatic compounds in agarwood essential oil in cosmetic products, perfumes, and pharmaceuticals.

“…The composition and content of essential oils depend on the species, extraction method, and soil of each region. For example, Marie-Laure Lota et al 9 The content of essential oils from varieties grown in France with higher levels of limonene, α-Pinene, Myrcene, and Sabinene than before (52.2-96.2%, 0.1-2, 1%, 1.3-1.8%, 0.1-1.3%, respectively). Gulay Kirbaslar et al 30 announced the composition of tangerine peel oil grown in Turkey obtained 45 compounds, of which, limonene (90.7%), followed by myrcene (2.1%), and α-pinene (0.5%).…”

“…Nowadays, fragrant compounds derived from nature are gaining great attention and becoming a trend, thus research on them is growing continuously [6][7][8][9] . Through previous studies and consumption practice, it has been shown that when using products of plant origin brings great effects with less toxicity and side effects.…”
