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 Kirsehir-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

Summary
Plants and their products in treatment of diseases have been used extensively by humans for many years [1]. Many higher plants have economically important compounds such as oils, resins, dyes, flavors and fragrances, pharmaceuticals, and pesticides. The antiseptic qualities of aromatic and medicinal plants and their extracts have been recognized since antiquity, while attempts to characterize these properties in the laboratory date back to the early 1900s [2]. Most species of higher plants have never been described, much less surveyed for chemical or biologically active constituents, and new sources of commercially valuable materials remain to be discovered. Medicinal plant products were gained great importance for use in medicine as natural products [3]
