title: Phenolic constituents from Dalbergia cochinchinensis.
abstract: Three new phenolic compounds (1-3), along with five known phenolics, 4'-hydroxy-2'-methoxychalcone (4), latinone (5), dalbergiphenol (6), 7-hydroxyflavanone, and dalbergin (7), have been isolated from the stems of Dalbergia cochinchinensis. The structures of 1-3 were established by spectroscopic techniques including 1D and 2D NMR methods. The inhibitory activity against testosterone 5 alpha-reductase, which causes androgen-dependent diseases, was also examined for selected compounds.
