Two new flavonoids, 3,4,10-trihydroxy-9-methoxypterocarpan and 2',4'-dihydroxy-4-methoxy-β-hydroxychacanonol, were isolated from Platymiscium floribundum, in addition to the homopterocarpin, 2',4',4-trihydroxychalcone, 7,3',5'-trihydroxyflavanone, 7,3'-dihydroxy-8,5'- dimethoxyisoflavanone, 8-hydroxy-5,6,7,-trimethoxycoumarin, 6-hydroxy-7,8- dimethoxycoumarin, 6,7,8-trimethoxycoumarin, 6,7-dimethoxycoumarin, 8-hydroxy-6,7-dimethoxycoumarin, 3β-acetoxy-28-hydroxyolean-12-ene, 1,2,3-trimethoxy-5-allyl-benzene, 3,4-dimethoxycinnamaldehyde, and β-sitosterol and stigmasterol as a mixture. Structural characterization of all compounds was established on the basis of spectroscopic methods, particularly 1D and 2D nuclear magnetic resonance (NMR) and comparison with data from literature. © 2012.
