Lambertianin C is an ellagitannin.

Natural occurrence

Lambertianin C can be found in Rubus species such as Rubus lambertianus,[2] in cloudberries (Rubus chamaemorus)[3] and in red raspberries (Rubus idaeus).[4]

Chemistry

Lambertianin C is trimer of casuarictin linked by sanguisorbic acid ester groups between glucopyranose moieties.[2] It contributes to the in vitro antioxidant activity of raspberries.[5]
