OBJECTIVE
To study the chemical constituents from leaves of Uraria lacei.
METHODS
Chemical constituents were isolated by silica gel column and Sephadex LH-20, and identified by physiochemical and spectral analyses and by comparison with the standard compounds.
RESULTS
Eleven compounds were isolated and identified as naringenin-7-0-beta-D-glucopyranside (1), (2S)-5, 7-dimethoxy-4'-hydroxyflavan (2), dalbergioidin (3), 5, 7-dihydroxy-2'-methoxy-3', 4'-methylenedioxyisoflavanone (4), apigenin (5), 5, 7-dihydroxy-2', 4'-dimethoxyisoflavanone (6), 5, 7, 2', 4'-tetrahydroxyisoflavone (7), emodin (8), saliylic acid (9), daucosterol (10), and tetracosane (11).
CONCLUSIONS
All compounds were isolated from this plant for the first time.
