Sanguiin H-6 is an ellagitannin.

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.

Sanguiin H-6 contributes to the antioxidant capacity of raspberries.[5]

It is an isomer of agrimoniin.[6]

gollark: Democratic ones theoretically allow more input from everyone, which should lead to decisions which consider their interests more and take into account information people know, but also run into whatever issues existing democracies have plus probably exciting new ones due to presumably having a direct democracy voting on a lot of things.
gollark: Hierarchical ones (theoretically) allow clear direction and management from the top but also lack input from lower levels and are vulnerable to the top people being wrong/bad.
gollark: Before trying to think of ideas for organization structure it might be good to clarify what exactly the organizational structure should do/allow/optimize.
