Ocotea odorifera (Vell.) Rohwer - syn. Ocotea pretiosa (Nees) Mez - Lauraceae
Brazilian sassafras, canela sassafraz (port.), Brasilianisches Sassafras

Dioecious tree, up to 15m tall, native to South America (Brazilian Atlantic rainforest); leaves alternate, oblong-lanceolate, glossy dark green; flowers small, yellowish, fruits oval, 2m in diam.

„…commonly known as Brazilian sassafras or American cinnamon; though it is not a true sassafras nor a true cinnamon…“ https://en.wikipedia.org/wiki/Ocotea_odorifera

The cinnamon-like odour and flavour of the wood and bark of one variety of O. pretiosa was found to be due to 1-nitro-2-phenylethane, also found in Aniba canelilla wood and bark. This compound is responsible for the cinnamon-like odour of both trees.

„Brazilian sassafras oil or, more correctly, ocotea oil… is obtained from wood of O.pretiosa ans is similar in its main components to true sassafras oil, for which it is generally substituted. The oil was initially and incorrectly described as from O.cymbarum…Oil yield varies form 0.9-2.0%… Ocotea oil is a pale to very pale oily liquid with a sweet, spicy, somewhat camphoraceous odour and a sweet, woody taste similar to sassafras oil. Its main constituent is safrole to 90%, with most other constituents [like alpha-pinene, eugenol, furfural, cineole e.g.] below 1%.“
[Weiss, Edward A. Essential oil crops. Cab International, 1997, 198-200]

The main constituents of the essential oil extracted from the leaves of Ocotea odorifera were safrole (36.3%), γ-cadinene (6.6%), camphor (6.5%) and α-copaene (6.0%).
