Methyl Hesperidin Chemical Identity
The PubChem record for methyl hesperidin gives the molecular formula C29H36O15 and a molecular weight of 624.6, one methylene unit more than hesperidin. The structure is hesperidin with an additional methyl ether on the B-ring, so the aglycone carries two methoxy groups where hesperidin carries one methoxy and one free hydroxyl. The rutinose sugar chain at position 7 is unchanged. Removing a free phenolic hydroxyl reduces hydrogen bonding in the crystal, which is part of the reason the solid dissolves more easily.
Trade names in this area are not uniform. Hesperidin methyl chalcone is a different material, an open-ring chalcone form that is also called methyl hesperidin in some lists, and it has its own identifier. The identifiers in the table belong to the PubChem record for methyl hesperidin, so a buyer who needs the chalcone should say so. The botanical origin is the peel of Citrus sinensis, which supplies the hesperidin precursor. Other citrus materials are listed as Citrus Bioflavonoids Extract 40–90% Total Bioflavonoids, Bitter Orange Peel Extract Powder and Citrus Bioflavonoid Extract Powder, none of which is a single methylated glycoside.
