Metabólitos secundários de Protium heptaphyllum march [PDF]

Química Nova, 2002
Phytochemical investigation of the resin, fruits, leaves, and trunk of Protium heptaphyllum led to the isolation of the monoterpene p-menth-3-ene-1,2,8-triol, a and b amyrin, quercetin, brein, quercetin-3-O-rhamnosyl, (-) catechin and scopoletin. Their structures were established by 1D and 2D NMR spectroscopy and comparison with published data.
