The root heartwood of Dalbergia odorifera T. CHEN (Leguminosae) is a Chinese medicinal drug (Japanese name koshinko) used for a stagnant blood syndrome (stagnation of disordered blood; Japanese, oketsu). In addition to 10 known compounds, five new phenolic compounds, isomucronustyrene and hydroxyobtustyrene (cinnamylphenols), (+)-isoduartin (isoflavan), odoriflavene (isoflav-3-ene) and (-)-odoricarpan (pterocarpan) were isolated and their structures were elucidated on the basis of chemical and spectroseopic methods. Of the fifteen compounds isolated, cinnamylphenols, isoflavans, isoflavene and benzoic acid derivative significantly inhibited prostaglandin biosynthesis as well as platelet aggregation induced by arachidonic acid.

Twenty-seven isoflavonoid monomer and dimer derivatives were obtained from the heartwood of Dalbergia odorifera T.CHEN (Leguminosae).The structure elucidation of twelve monomeric and five dimeric isoflavonoids is dealt with in this paper, affording novel examples of naturally occurring biisoflavonoids.Keywords: Dalbergia odorifera; Leguminosae; isoflavonoid; biisoflavonoid; (3R)-vestitol; (3R)-claussequinone; formononetin; bowdichione; liquiritigenin; isoliquiritigenin; medicarpin; X-ray analysis
