Abstrak

Four flavonoid glycosides have been isolated from the leaves of Crotalaria anagyroides. The glycosides are 1) apigenin 7-O-β-D-apiofuranosyl (1!6)-β-glucopyranosida, 2) apigenin 7-O-β-D-apiofuranosyl (1!2)-β-glucopyranoside, 3)chrysoeriol 7-O-β-D-apiofuranosyl (1!6)-β-D-glucopyranoside, 4) chrysoeriol 7-O-β-D-apiofuranosil (1!2)-β-D-glucopyranoside. Their structures were elucidated by spectroscopic methods of UV,  1H,  13C and 2D-NMR DEPT, COSY and HMBC experiments.Key-words: Crotalaria anagyroides, apiin, apigenin 7-O-β-D-apiofuranosyl (1!6)-β-glucopyranosida, Chrysoeriol 7-O-β-D-apiofuranosyl(1!2)-β-D-glucopiranosida.
