Natural occurrence

Sanguiin H-6 can be found in Rosaceae such as the great burnet (Sanguisorba officinalis),^[1] in strawberries (Fragaria × ananassa)^[2] and in Rubus species such as red raspberries (Rubus idaeus)^[3][4] or cloudberries (Rubus chamaemorus).^[4]

Chemistry

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.^[5] Sanguiin H-6 contributes to the in vitro antioxidant activity of raspberries.^[6]
