Polymethoxyflavones in peel of Citrus reticulata ‘Chachi’ and their biological activities

Citrus polymethoxyflavones (PMFs) have been of increasing interest due to their extensive biological activities. In the present study, a total of eight PMFs were isolated from the peel of Citrus reticulata ‘Chachi’ (CRC). They were individually identified as 5-hydroxy-6,7,8,4′-tetramethoxyflavone (1), 5,6,7,3′,4′-pentamethoxyflavanone (2), 5-hydroxy-6,7,8,3′,4′-pentamethoxyflavone (3), 3,5,6,7,8,3′,4′- heptamethoxyflavone (4),...
