New flavones, 5, 6, 7, 3', 4', 5'-hexamethoxy, 3', 4'-methylenedioxy-5, 6, 7, 5'-tetramethoxy, and 3', 4'-methylenedioxy-5, 7, 5'-trimethoxyflavone isolated from Bauhinia championii, were synthesized to confirm their structures. These synthesized flavones were identified with the natural fiavones by the physical and spectral data. A new preparation of 3, 4-methylenedioxy-5-methoxybenzaldehyde was also discussed.
