OBJECTIVE
To separate effective constituents from Millettia nitida var. hirsutissima.
METHODS
Compounds were isolated by chromatography methods, structures were identified by spectroscopic means.
RESULTS
Eight flavonoids (1-8) and two triterpenes (9-10) were isolated from this plant. They were identified as calycosin (1), genistin (2), gliricidin (3), 8-O-methylretusin (4), afromosin-7-O-beta-D-glucopyranoside (5), lanceolarin (6), soliquiritigenin (7), symplocoside (8), lupeol (9), 3beta-friedelanol (10).
CONCLUSIONS
The compounds (1-10) were obtained from M. nitida var. hirsutissima for the first time. The 13C-NMR dada of 1 were correct assignment on the basis of 2D-NMR spectral analysis.
