Infobox references

Lambertianin C is an ellagitannin.

Natural occurrences

Lambertianin C can be found in Rubus species such as Rubus lambertianus,[1] in cloudberries (Rubus chamaemorus)[2] and in red raspberries (Rubus idaeus).[3]

Chemistry

Lambertianin C is trimer of casuarictin linked by sanguisorbic acid ester groups between glucopyranose moieties.[1]

Health effects

It is a molecule responsible for the antioxidant capacity of raspberries.[4]
