Sanguiin H-6 is an ellagitannin.
Sanguiin H-6 can be found in Rosaceae such as the great burnet (Sanguisorba officinalis), in strawberries (Fragaria ÃÂ 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 in vitro antioxidant activity of raspberries.
