Sanguiin H-6 is an ellagitannin.

Natural occurrence

[edit]

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

[edit]

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]
