Abstract:
Objective: To investigate the isoflavonoids from Dalbergia cochinchinensis. Methods: To isolate and purify the compounds by various column chromatographic methods. Spectral analysis was used to identify the structures. Results: Fourteen isoflavonoids were isolated and identified as sativanone (1), 7-hydroxy-2',4'-dimethoxyisoflavan (2), 4,7,2'-trihydroxy-4'- methoxyisoflavanol (3), 5,7-dihydroxy-2',3',4'-trimethoxyisoflavanone (4), formononetin (5), 2'-hydroxyformonetin (6), 2',5,7- trihydroxy-4'-methoxyisoflavone (7), genistein (8), 3'-O-methylviolanone (9), 3-hydroxyvestitone (10), biochanin A (11), homoferreirin (12), medicarpin (13), and isodarparvinol B (14), respectively. Conclusion: Compounds 3, 4, and 12 are isolated from the plants of Dalbergia Linn. f. for the first time, and compounds 1-2, 6-11, and 13-14 are isolated from this plant for the first time.
