Chemical Component Identification of Four Agarwood Grades : Kacangan A. Teri B. Kamedangan A and Kamedangan B

Agaruood signifies as one of the non-timber forestproducts (NTFPs) comodities in Indonesia.The-form of aganvood varies, such as lumps, chips,flour, until oil Aganvood in incense shape will give eff smells, if burnt. This experiment aimed to identify chemical components in four grades of agaruood from the best to the loses: i.e. kacangan B, teri B, kamedangan A dan kamedangan B.Identification was petformed by extracting the agaruood with acetone solvent, and then the acetone extract n/as fractionated using gradient column chromatography method 1JJith n• hexane-ethyl acetate as elueru.
