Two new isoflavonoids, named 6,7,2′-trihydroxy-4′-methoxyisoflavone (1), 7,3′-dimethoxy-5′-hydroxyisoflavone (2), one new norneolignan, named (8S)-2,4-dihydroxy-8-hydroxymethyl-4′-methoxydeoxybenzoin (3); together with six known compounds, methyl 4-hydroxylbenzoate (4), ethyl 4-hydroxybenzoate (5), piceatannol (6), cararosin A (7), 2,4-dihydroxybenzoate (8), and 6,7,4′-trihydroxyisoflavone (9) were isolated from the red heartwood in the rhizomes of Caragana changduensis by using chromatographic methods Their structures were determined by extensive spectroscopic analysis and comparison of their spectral data with previous reported data.
