Abstract This study evaluated, for the first time, the phenolic content of white ( Morus alba ) and black mulberry ( Morus nigra ) fruits with proven market aptitudes and grown in Spain, one of the main European producers. The antioxidant activity and mineral composition of these promising berry fruits were also assessed. Black mulberry clones showed higher antioxidant activity and amounts of phenolic compounds than white mulberry clones, although a wide intra-species variability was noted, according to principal component analysis. The total anthocyanins varied significantly among clones of M. nigra . These results are keys for the design of future dietary intervention studies examining the role of mulberry fruits in disease risk reduction. They can also be used for the development of mulberry derived-products rich in phenolic compounds.
