Figure 1
The structures of the flavonoids that inhibited glycation. 1: Plantagoside (R = glucose), 2: 5,7,3′,4′,5′-pentahydroxyflavanone (R = H), 3: 5,7-dihydroxy-3′,4′,5′-trimethoxyflavone (R1 = R2 = CH3), 4: 5,7,3′,4′,5′-pentahydroxyflavone (R1 = R2 = H), 5: 5,7,4′,5′-tetrahydroxyflavone-3′-O-glucoside (R1 = glucose, R2 = H), 6: myricetin, and 7: dihydromyricetin.
