{{:nerolidol_e.jpg|}} (E)-nerolidol

Cabreuva oil is obtained from Myrocarpus fastigiatus by steam distillation of the wood. It is used in perfumery due to its pleasant smell (tender balsamic, dusty floral, somewhat herbal and woody). Main compounds in Brazilian cabreuva oil were (E)-nerolidol (77.0%), (E,E)-farnesol (2.1%), (Z,E)-farnesol (1.1%), and α-bisabolol (1.6%). \\
