Evaluation of Antioxidant, Antibiofilm, and Mutagenic Properties of Different Grape Fruits

Grape is a plant belonging to the Vitis genus of the Vitaceae family and has thousands of different varieties grown in many regions of the world. In this study, total phenolic content, total flavonoid content, antioxidant activity, antibiofilm activity and mutagenic activity values of pericarp samples of Banazı karası, Köhnü, Kureyş, Pütürge Kırmızısı, Hatun parmağı, Gelin parmağı, Boğazkere, Mikeri, Mazıkıran, Aşık beyazı, Asmalık, Ternebi, Şam, Öküzgözü, İzmir and Çekirdeksiz grape varieties grown in Malatya/Türkiye were studied. The highest total phenolic content, DPPH and ABTS radical scavenging activity and FRAP values were determined in the Mazıkıran variety (163.6 mg/g, 52.8%, 48.2% and 264.2 µmol/g), the highest total flavonoid content was determined in the Gelin parmağı variety (26.4 mg/100 g). It was observed that fruit extracts of all varieties had different levels of antibiofilm activity against Listeria monocytogenes ATCC 19115 at different content amounts. However, it was determined that fruit extracts of Hatun parmağı, Banazı karası, Mazıkıran, Mikeri and İzmir varieties showed over 90% antibiofilm activity. 50 and 100 µL/plate doses of fruit extracts tested in Pütürge Kırmızısı samples showed mutagenic properties in TA98 and TA100 strains compared to the control.
