Antioxidant activity and phytochemical characterization of Cornus mas fruit and its products

Cornus mas fruits, called cornelian cherries, are usually used in cuisine or in a traditional medicine. The aim of this research was to determine its potential as a source of bioactive phytochemicals for enrichment of food products. Two different local Cornus mas fruit samples, as well as three plum jams with different ratios of plum/cornelian cherry fruits (v/v 90/10, 80/20 and 50/50), and the honey macerated with fruits were analysed with DPPH and Folin Ciocalteu total phenol assays. Additionally, phytochemical profile was determined by direct injection quadrupole-time of flight mass spectrometry (Q- TOF MS). In raw Cornus mas fruits several anthocyanins (pelargonidin, delphinidin and cyanindin glycosides) and two iridoids (cornuside and loganic acid) were identified. Results revealed that addition of Cornus mas fruits to the plum jam highly influence its total phenolic content and antioxidant capacity, whereas the highest results were obtained for the jam with the highest share of Cornus mas fruits (total phenols 2108.68 mg GAE/kg, antioxidant capacity 6.30 mmol trolox/kg). Additionally, this jam had specific phenols such as pelargonidin-3-O-glucoside, cyanindin-3-O- galactoside and cyanidin-3-O-rutinoside. The present research confirmed the potential of the Cornus mas fruits as a source of bioactive compounds for production of functional foods.
