Three new C-glycosidic flavonoids, cassiaoccidentalins A, B and C, were isolated from aerial parts of Cassia occidentalis, and their structures with a 3-keto sugar were established on the basis of spectroscopic and chemical evidence. They showed signals of two conformers in their ¹H- and ¹³C-NMR spectra due to hindered rotation around their C-glycosidic linkages, and the conformations in solution were analyzed by NMR spectroscopic analyses.
