ABSTRACT
To study the chemical constituents of the Maackia amurensis, the constituents were isolated by various chromatographies and the structures were elucidated on the basis of chemical and spectroscopic data (ESI-MS, 1D and 2D NMR). Thirteen isoflavone glycosides were isolated from the n-BuOH-soluble fraction of the 70% ethanol extract and identified as 7-hydroxy-4',6-dimethoxyisoflavone-7-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (1), dalsympathetin (2), ononin (3), glycitin (4), genestin (5), saikoisoflavonoside A (6), afrormosin-7-O-beta-D-glucopyranoside (7), gehuain (8), kushenol O (9), 7-hydroxy-4',6-dimethoxyisoflavone-7-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranoside (10), tectoridin (11), biochanin A 7-O-beta-D-gentiobioside (12) and 7-hydroxy-4'-methoxyisoflavone-7-O-beta-D-apiofuranosy l-(1-->6)-beta-D-glucopyranoside (13). Compound 1 is a new isoflavone glycoside, named as maackiaisoflavonoside, compounds 2, 8, 9, 10, 12 and 13 were isolated from this genus for the first time.
