ABSTRACT
Upon hydrodistillation of Malaysian ‘gaharu’ (agarwood), an essential oil is obtained in 0.8% yield. The odour of the oil can be described as warm, diffusive, strongly woody and characteristic. It was found to contain at least 61% sesquiterpene alcohols, with 10-epi γ - eudesmol (23%) and valerianol (12.3%) predominating. The remaining part of the oils is made of sesquiterpene oxides (α - agarofurane : 7.5% major) and a number of non terpenic aromatic compounds (benzylacetone: major). These findings and other considerations conform the identity of the starting material is Aquilaria malaccensis Benth.
ABSTRAK
Penyulingan hidro ke atas kayu gaharu telah menghasilkan 0.8% minyak pari. Bau minyak gaharu ini boleh disifatkan sebagai ‘suam’ meresap dan kekayuan. Isi kandungan minyak ini didapati terdiri daripada 61% alcohol seskuiterpena, yang 10–epi γ-eudesmol (23%) dan valerianol (12.3%) adalah kandungan utama. Komponen-komponen lain di dalam minyak pati adalah seskuiterpena oksida (α - agrofuran: 7.5% utama) dan beberapa bahan aromatik bukan terpena (benzilaseton: utama). Kajian ini bersama analisis data berkaitan telah mengenalpasti bahawa bahan kajian adalah Aquilaria malaccensis Benth.
