Isoorientin

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] Studies also showed that isoorientin is a potential neuroprotective compound against Alzheimer's disease.^[2]
