Studies for determining and identifying the content of antocyanic pigments in some species of wild fruits originated in Neamt County (2004)

Abstract

The biological material analysed in this study has been sampled from different localities of the Neamţ County. In wild cherry and raspberry, the sampled harvesting was carried out at two different ripeness periods, for comparing the results. Wild blackberries contained a major pigment (cyanidine 3 glicoside) at a percentage of almost 90% of the whole antocyans present in fruits. Wild black cherries had three major characteristic pigments: peonidine-3-rutinoside (the highest percentage), followed by cyanidine-3-glucoside and peonidine-3-gluoside (the lowest percentage). In raspberry, we have identified the following pigments: cyanidine-3-sophoroside (major pigment) at a percentage of almost 50%, cyanidine-3-glucosidrutinosode and cyanidine-3-rutinoside. In blueberries, over 14 pigments could be found as distinct peaks. We have also identified the pigment cyanidine-3-glicoside, which was one of the most important. In case of blueberries, by comparing the own chromatogram to already published chromatograms and analysing the results, we could assess that main differences were found between the percentage of antocyans present in the cultivated varieties, respectively, the spontaneous flora. It also appeared the differentiation according to geographical area and species.
