The Kintamani community in Bali uses the Solanum betaceum as a vegetable or herbal medicine to treat sprue disease. This study aims to isolate flavonoid glycosides and prove the activity of flavonoid glycoside extract of n-butanol, as an antioxidant. The separation of n-butanol extracts was carried out by column chromatography and then identified by FTIR, UV-Vis and LC-MS/MS spectrometry. Three flavonoid glycosides were isolated and identified from 5 and 6 fractions of n butanol extract namely Quercetin 3-O rhamnoside, Routine and Kaempferol 3-O rutinoside. The three flavonoid glycoside compounds have strong antioxidant activity with DPPH Test. These results indicated the potential of terong belanda fruit as a source of natural antioxidants for health management. https://biomedpharmajournal.org/vol11no4/the-flavonoid-glycosides-antioxidant-from-terong-belanda-solanum-betaceum/ Antioxidant Flavonoid glycosides Solanum Betaceum Cav
