Aniba rosaedora

Aniba rosaedora (family Lauraceae) Mostly distributed in South America. Rosewood is a wild evergreen tree in Brazil and Peru. The oil is used for artificial flavours, in the perfume and soap industries. 

Structurally, the only unusual chalcone of woody tissues is rubranine (30) from Aniba rosaedora, which is a citral-chalcone condensation product. The possibility of rubranine being an artifact of the isolation procedure was considered by Montero and Winternitz (28), who synthesized it by condensing the essential oil citral with pinocembrin in the presence of the alkaloid anibine, which also occurs naturally in Aniba wood. However, De Alleluia and coworkers (7) later confirmed that it was a natural product from the evidence that it was optically active, and that it could be isolated by very brief washing of the wood with hexane.
