Litsea cubeba oil, distilled from the fruits (3-5%), contains mainly citral. „Its major use, however, both in the People's Republic of China and in international markets, is as a raw material source for the isolation of citral. This is used in its own right for flavour and fragrance purposes or converted by the chemical industry to a number of important derivatives such as ionones, which possess a violet-like fragrance, and vitamins. “ http://www.fao.org/docrep/V5350e/V5350e09.htm
„The major components in the oils from roots and fruits, from stems, leaves, and alabastra, and from flowers were citral B (neral), β-phellandrene, and β-terpinene, respectively.“
