Chemical composition and antioxidant activity of seven different grape extracts

Abstract

Grape extracts have strong antioxidant potential which can make them promising anticancer and food-supplement. However, one of the main obstacles is that there is not enough data revealing content of the grape extracts. Another important issue is that grape extracts are mostly obtained in methanol and ethanol solvent, which can limit their effective usage. Therefore, in this study, extracts of seven different grape species of white and red grape (which were collected from Kırşehir-Toklumen) were collected using 70:30 water:ethanol, which underwent GC-EI-MS characterization. GC-MS based characterization revealed that the species had key content differences and similarities, which can trigger further research to quantify the content to reveal what exactly brought the differences in the obtained antioxidant potential of the grape species
