Isoorientin (or homoorientin) is a flavone, a chemical flavonoid-like compound. It is the luteolin-6-C-glucoside. Bioassay-directed fractionation techniques led to isolation of isoorientin as the main hypoglycaemic component in Gentiana olivieri.[1]

Natural occurrences[edit]

Isoorientin can be isolated from the passion flower, Vitex negundo, Terminalia myriocarpa, the Açaí palm and Swertia japonica.
