Hawaiian Sandalwood: Oil Composition of Santalum paniculatum and Comparison with Other Sandal Species

Four commercial qualities of Hawaiian sandalwood oil produced from wood of Santalum paniculatum originating from the island of Hawaii (“The Big Island”) were analyzed using GC and GC-MS. Main constituents of the oils were ( Z)-α-santalol (34.5–40.4%) and ( Z)-β-santalol (11.0–16.2%). An odor evaluation of the oils was carried out against East Indian sandalwood oil. In addition, the chemical composition of Hawaiian sandalwood oil was compared with four different Santalum species originating from East India, New Caledonia, Eastern Polynesia and Australia, respectively.
