Abstract

Grape skins and seeds are sources of various quality characters of grapevine varieties, such as phenolic compounds, anthocyanins, resveratrol etc. The Greek vineyard is characterized by a large number of indigenous grapevine varieties which remain almost unexploited in terms of their different phenolic content. The aim of this study was to assay the polyphenolic content of seven red native Greek grapevine varieties (‘Kolliniatiko’, ‘Bekari’, ‘Bakouri’, ‘Kountoura mavri’, ‘Doubrena mavri’, ‘Thrapsa’, and ‘Mavro Spetson’) using high performance liquid chromatography (HPLC) coupled with a diode array detector and spectrophotometer. All studied varieties were cultivated in the same area and under the same conditions. The results revealed that despite the fact that anthocyanins and phenolic compounds content were in high levels for all varieties, statistically significant differences were recorded among them. The highest anthocyanins concentration was recorded in ‘Kolliniatiko’, while the lowest anthocyanins concentration was recorded in ‘Mavro Spetson’. Grapevine variety ‘Mavro Spetson’ presented the highest concentration of total phenolic compounds, with statistically significant difference compared to ‘Kountoura mavri’ and ‘Bekari’. Grapevine varieties ‘Kolliniatiko’ and ‘Bekari’ presented the highest concentrations in trans-resveratrol and piceid content, while grapevine variety ‘Doubrena mavri’ presented the highest concentration in vanillin content. These unexploited rare native cultivated varieties contained appreciable amounts of non-colored phenols as well as anthocyanins, meaning that they would be worthy of further study and use for the production of quality wines.
