The anthocyanin content and bioactivity of cornelian cherry (Cornus mas) and wild blackberry (Rubus fruticosus): Fruit extracts from the Vlasina region

Abstract

The aim of this study was to assess antioxidant and antimicrobial activities of anthocyanin rich extracts of two wild berry fruit species from the Vlasina region, namely, cornelian cherry (Cornus mas) and wild blackberry (Rubus fruticosus). The phenol and anthocyanin content was determined using spectrophotometric and high performance liquid chromatography (HPLC) assays. The antioxidant activity was estimated by 2,2'- diphenyl-1-picrylhydrazyl (DPPH) assay, while disc diffusion and broth microdilution tests were carried out to determine the antimicrobial activity. All extracts showed high radical scavenging activity and antimicrobial activity on all tested bacterial strains. The extracts of wild berry fruits can be suitable for the preparation of different nutritional and pharmaceutical ingredients.
