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.
