title: Polyphenols pattern and correlation with antioxidant activities of berries extracts from four different populations of Sicilian Sambucus nigra L.
abstract: Sambucus nigra L. (Caprifoliaceae) is wide spread in temperate and sub-tropical zones. The consumption of its berries has been associated with health benefits especially for its high content of natural antioxidants such as polyphenols, in particular anthocyanins. In this work we investigated the polyphenolic composition and the in vitro antioxidant activities (ABTS, DPPH, BCB and FRAP-ferrozine (FRAP-FZ) assays) of S. nigra berries, collected in four different Sicilian areas (Italy). Elderberries are considered one of the fruits with highest anthocyanins content, the amount of phenolic compounds, other than anthocyanins, is approximately 1.5 times greater than the latter. The LC-MS analyses have revealed an opposite trend in the polyphenols pattern in Sicilian populations. Moreover, a statistical correlation was found between cyanidin-3-sambubioside-5-glucoside and antioxidant activity evaluated by FRAP-FZ and ABTS assays. In conclusion, Sicilian S. nigra berries are appealing for its antioxidant potential and for its particularly high content of anthocyanins.
