Viburnum opulus L.with the common name Gilaburu belong to the family of Caprifoliaceae. This plants is widely grown
particularly in Kayseri region in Turkey. Gilaburu fruits are traditionally used in the treatment of kidney problems and kidney
stones. Additionally, it has sedative effects, acts as a vasodilator and an effective antispasmodic that helps to relieve muscle
cramps and spasms (1). Fresh and fermented Gilaburu fruits were extracted with methanol (40 C) in a ultrasonic bath
(Heidolph, America) for 1 hours. Filtered extracts were evaporated and dissolved with methanol for antioxidant activity. The
extracts were analyzed by high-performance liquid chromatography with diode array detector (HPLC-DAD) to identify and
quantify their phenolic compounds. Antioxidant potential of the methanol extracts of fresh and fermented Gilaburu fruits were
characterized with total phenolic content (TPC), total flavonoid content (TFC), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and
ABTS [2,20 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)]. Gallic acid, chlorogenic acid, 2,5-dihydroxybenzoic acid,
caffeic acid, rutin, p-coumaric acid, quercetin, kaempferol and isorhamnetin were detected in different amounts in the all
extracts. Fermentation process positively influenced total phenolic and total flavonoid content, DPPH radical scavenging
activity, ABTS+
activity
