Sanguiin H-6

Sanguiin H-6 is an ellagitannin. Sanguiin H-6 is an ellagitannin. Sanguiin H-6 can be found in Rosaceae such as the great burnet (Sanguisorba officinalis), in strawberries (Fragaria × ananassa) and in Rubus species such as red raspberries (Rubus idaeus) or cloudberries (Rubus chamaemorus). Sanguiin H-6 is dimer of casuarictin linked by a bond between the gallic acid residue and one of the hexahydroxydiphenic acid units. It has sanguisorbic acid ester groups as linking units between glucopyranose moieties. Sanguiin H-6 contributes to the antioxidant capacity of raspberries. It is an isomer of agrimoniin.
