Chemical Constituents of Essential Oils from Resin and Bark of Agathis borneensis

Abstract

The chemical constituents of essential oils obtained from resin and bark of Agathis borneensis were analysed using capillary gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometer (GC/MS). The resin essential oil dominated by α-pinene (30.93%), δ-limonene (17.79%), β-pinene (11.28%) and terpinen-4-ol (8.35%). The main components in the bark essential oil were β-pinene (8.68%), terpinen-4-ol (8.54%), α-pinene (8.50%) and α-terpineol (8.48%).
