title: Anthocyanin determination in blueberry extracts from various cultivars and their antiproliferative and apoptotic properties in B16-F10 metastatic murine melanoma cells.
abstract: Blueberry consumption is associated with health benefits contributing to a reduced risk for cardiovascular disease, diabetes and cancer. The aim of this study was to determine the anthocyanin profile of blueberry extracts and to evaluate their effects on B16-F10 metastatic melanoma murine cells. Seven blueberry cultivars cultivated in Romania were used. The blueberry extracts were purified over an Amberlite XAD-7 resin and a Sephadex LH-20 column, in order to obtain the anthocyanin rich fractions (ARF). The antioxidant activity of the ARF of all cultivars was evaluated by ABTS, CUPRAC and ORAC assays. High performance liquid chromatography followed by electrospray ionization mass spectrometry (HPLC-ESI-MS) was used to identify and quantify individual anthocyanins. The anthocyanin content of tested cultivars ranged from 101.88 to 195.01 mg malvidin-3-glucoside/100g fresh weight. The anthocyanin rich-fraction obtained from cultivar Torro (ARF-T) was shown to have the highest anthocyanin content and antioxidant activity, and inhibited B16-F10 melanoma murine cells proliferation at concentrations higher than 500 μg/ml. In addition, ARF-T stimulated apoptosis and increased total LDH activity in metastatic B16-F10 melanoma murine cells. These results indicate that the anthocyanins from blueberry cultivar could be used as a chemopreventive or adjuvant treatment for metastasis control.
