The niaouli oil-producing Melaleuca viridiflora grows in North and West Australia and is grown in plantations in New Guinea and Vietnam. Concerning the composition of niaouli oil and data presented thereof, delineation of M. viridiflora to M. quinquenervia is often not made and there are also several chemotypes. Niaouli oils traded often come from New Caledonia or Madagascar, and contain cineol in the range of 35-65%. Other important components are the monoterpenes α-pinene, β-pinene, limonene, and α-terpineol as well as the sesquiterpene viridiflorol. There are also niaouli oils with low cineol content, but rich in nerolidol, linalool or viridiflorol.
