Cyanidin-3-O-sambubioside-5-O-glucoside(Cyanidin-3-O-sambubioside-5-O-glucoside chloride), cyanidin-3-O-sambubioside and cyanidin-3-O-glucoside were found and identified by HPLC-Q/TOF-MS as major anthocyanins and were quantified by HPLC-UV/Vis. In optimum maturity stage, ‘Samocco’ showed the highest anthocyanin content with an average of 1237 mg per 100 g dry weight in both growing areas and vintages. The dominant anthocyanin component of Samocco variety was cyanidin-3-O-sambubioside, which is according to literature more stable against technology processing than cyanidin-3-O-glucoside found in the other four investigated elderberry varieties in the highest concentration.
CONCLUSIONS:
'Samocco' had higher levels of total anthocyanins compared with most other cultivars at the two locations. Anthocyanin content was influenced by change of pH value and by heat treatment. After heat treatment, the highest anthocyanin concentration was observed at pH 3.5 with 'Haschberg', and at pH 3.0 with 'Samocco'. Total anthocyanin content was decreased 7% by heat treatment with 'Haschberg' and by 25% with 'Samocco' at the original pH value of 4.0. |
