Two novel pterocarpans, 8-hydroxy-3,9-dimethoxy- and 3,8-dihydroxy-9-methoxypterocarpan and a new santal analogue were isolated from the heartwood of P. soyauxii.These are accompanied by several known pterocarpans, isoflavans, isoflavones and trans-pterostilbene.From the heartwood of P. marsupium were obtained 8-C-β-D-glucopyranosyl-3,7,4'-trihydroxy- and -3,7,3',4'-tetrahydroxyflavone, representative of the first 5-deoxy C-C-coupled flavonol glucosides, and the rare 3'-C-β-D-glucopyranosyl-α-hydroxydihydrochalcone, their structures being determined by means of high resolution NMR techniques. Key Word Index--Pterocarpus soyauxii; P. marsupium; Leguminosae; isoflavonoids; 3'-C-glucosyl-α-hydroxydihydrochalcone; 5-deoxy-8C-glucosylflavonols.
