Abstract

From the peels of Citrus hassaku HORT. ex TANAKA (Rutaceae), eight flavonoid aglycones were isolated and characterized as 4', 5, 6, 7, 8-pentamethoxyflavone (I), 3', 4', 5, 6, 7, 8-hexamethoxyflavone (II), 3, 3', 4', 5, 6, 7, 8-heptamethoxyflavone (III), 3', 4', 5, 6, 7-pentamethoxyflavone (IV), 4', 5, 7-trimethoxyflavone (V), 3, 3', 4, ', 5, 7, 8-hexamethoxyflavone (VI), 4', 5, 7, 8-tetramethoxyflavone (VII) and 3', 4', 5, 7, 8-pentamethoxyflavone (VIII), based on spectral and chemical data.
