Analysis of polyphenolic content and antioxidant capacity of Cabernet Franc berries in different terrain conditions
To understand the difference in the phenolic compounds and antioxidant activities of Cabernet Franc berries where were from two different terrain vineyards in the Loess Plateau region, the physicochemical index, antioxidant activities, the phenolic composition and concentration of grape samples were determined. The results showed that the different kind of phenolic compound contents of grape berries were not uniform variation law； The antioxidant activities of slope land berries was lower than the flat land berries； The total 17 individual anthocyanin compounds were identified in flat and slope land berries (including 12 anthocyanin deriatives and 5 basic anthocyanins); Terrain conditions had no effect on anthocyanin composition, but had effect on anthocyanin concentration in different extent; The concentration of 5 basic anthocyanins from slope land vineyard berries were higher than flat land berries. So the terrain condition of vineyard could really influence the phenolics composition and content, antioxidant activity of Cabernet Franc berries.
