Myrocarpus fastigiatus Allemão - Fabaceae - cabreuva, Cabreúva tree, óleo-pardo (port.), cabureiba (port.), **Cabreuva** Endangered tropical tree, native to South America (southern Brazil). CAS numbers: 68188-03-4 M.frondosus and M.fastigiatus wood oil; 91722-94-0 Myrocarpus frondosus wood oil; 91722-93-9 Myrocarpus fastigiatus wood oil. "The main natural sources of (+)-(E)-nerolidol are cabreuva oil from Myrocarpus frondosus and M.fastigiatus, and Peru balsam from Myroxylon pereira." \\ [[https://de.wikipedia.org/wiki/Nerolidol|Nerolidol]] stereoisomers are described as: (-)-(Z) intensive, flowery, sweet, fresh; (+)-(Z) woody, green, like fresh bark; (-)-(E) pleasant, woody, warm, musty; (+)-(E) slightly sweet, mild, soft, flowery, different to (Z )-(-), less intensive. \\ [The stereoisomers of nerolidol: separation, analysis and olfactoric properties., Schubert, V., Dietrich, A., Ulrich, T., Mosandl, A., Zeitschrift für Naturforschung C, 47(3-4), 1992, 304-307] {{: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%). \\ [Wanner, J.K.R., et al., Chemical composition, olfactory analysis and antibacterial activity of selected essential oils (mainly used in perfumery products).
