Lambertianin C is an ellagitannin.

Natural occurrences[edit]

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[edit]

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

Health effects[edit]

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