From the heartwood of Lindera glauca Blume three new diarylpropanoids have been isolated and identified, which were named lindeglaucol, lindeglaucone, and lindeglaucoside A. Chipped heartwood was extracted repeatedly with 80% aqueous methanol (MeOH) at room temperature, and the concentrated methanolic extract was successively partitioned with ethyl acetate (EtOAc), n-butanol, and H2O. From the EtOAc fraction, three new diarylpropanoids and a known chalconoid were isolated through repeated column chromatography with silica gel, octadecyl silica gel, and Sephadex LH-20. The chemical structures of the compounds were elucidated by interpretation of extensive spectroscopic data such as nuclear magnetic resonance, fast atom bombardment mass spectroscopy, and infrared. In addition, a known chalconoid, cilicicone B, was isolated for the first time from the heartwood of L. glauca
