Hesperetin 7-O-glucoside

Hesperetin 7-O-glucoside and prunin are direct precursors of naringin and neohesperidin, respectively, in C. aurantium. Hesperetin 7-O-glucoside shows inhibition of human HMG-CoA reductase, it also exhibits effective inhibition of the growth of Helicobacter pylori. Hesperetin 7-O-glucoside can reduce blood pressure in healthy volunteers.Hesperetin 7-O-glucoside (Hes-7-G) was produced by the enzymatic conversion of hesperidin by Aspergillus sojae naringinase due to the removal of the terminal rhamnose.Extracts from orange juice and peel containing the hesperidin were so treated by this enzyme that the hesperidin could also be converted to Hesperetin 7-O-glucoside . The solubility of Hesperetin 7-O-glucoside in 10% ethanol was enhanced 55- and 88-fold over those of hesperidin and hesperetin, respectively, which may make Hesperetin 7-O-glucoside more bioavailable. Hesperetin 7-O-glucoside was 1.7- and 2.4-fold better than hesperidin and hesperetin, respectively, in the inhibition of human intestinal maltase. Hesperetin 7-O-glucoside was more potent by 2- and 4-fold than hesperidin in the inhibition of human HMG-CoA reductase. Additionally, Hesperetin 7-O-glucoside exhibited more effective inhibition of the growth of Helicobacter pylori than hesperetin, while its effectiveness was similar to that of hesperidin.
