The popularity of edible wild fruits has increased in industrialized countries due to their composition and positive effects. The aim of this study has been to characterize the polyphenolics and anthocyanins of black mulberry (Morus nigra L.), cornelian cherry (Cornus mas L.), elderberry (Sambucus nigra L.), hawthorn (Crataegus monogyna L.), lingonberry (Vaccinium vitis-idaea L.) and rose hip (Rosa canina L.) harvested in the north-west of Italy by means of HPLC-DAD-ESI HRMS in positive ion mode. Although there is an abundant amount of literature related to the polyphenolics of cultivated fruit, a new type of comparison has here been conducted between wild and cultivated fruits on their polyphenolic content. The HPLC-DAD-ESI HRMS method has detected 64 different polyphenolic molecules and it can be used to perform qualitative and quantitative analyses. Furthermore, the cornelian cherry and elderberry samples showed the highest polyphenolic compound levels. The quercetin glycosylated compounds showed the highest percentage of flavonols in most of the analyzed wild fruits.
