摘要: Previous phytochemical studies on residues of pau-rainha’s heartwood (Brosimum rubescens) showed a high content xanthyletin, coumarin with biological potential. Continuing our sawdust this species, work relates the basic density, isolation and identification triterpene 3β-acetoxy-olean-12-ene-28-al β-sitosterol in n-hexane MeOH extracts plant´s sapwood. The structure was determined basis NMR spectra 1D (1H 13C) 2D (HSQC HMBC) comparison literature data. density found for sapwood 0.58 g cm-3, that even so is inferior one heartwood, could be used confection some products, also marquetry techniques.
