A new flavanone, 5-hydroxy-7,2′,3′,4′,5′,6′-hexamethoxyflavanone (1), was isolated from the unripe fruit peels of Citrus reticulata (Rutaceae), together with two known polymethoxyflavones, 5,6,7,8,3′,4′ -hexamethoxyflavone (2) and 5,6,7,8,4′-pentamethoxyflavone (3). The structure of 1 was characterized and identified by spectral analysis.
