Analysis volatile compound of gaharu oil composition via solid phase micro extraction (SPME)

Gaharu (agarwood) is a fragrant wood that is usually derived from the diseased timber of the genus Aquilaria Thymelaeceae and often occurs as dark coloured patches or streaks in the tree. Due to its strong, unique scent and medicinal properties, gaharu oil is greatly valued as perfumery ingredient a...
