semisynthesis of neohesperidose was performed in three-steps with 43% overall yield starting from naringin, the main flavonoid of grapefruit. In addition, the behaviour of two pairs of flavonoid 7-O-rhamnoglucosides (neohesperidosides naringin and rhoifolin; rutinosides hesperidin and diosmin) under same acetolysis conditions was compared. Results demonstrated the crucial influence of the oxidation state
