Isoorientin
Introduction '''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''. Studies also showed that isoorientin is a potential neuroprotective compound against Alzheimer's disease.
Natural occurrences Isoorientin can be isolated from the passion flower, ''Vitex negundo'', ''Terminalia myriocarpa'', the Açaí palm and ''Swertia japonica''.
Metabolism * Isoorientin 3'-O-methyltransferase
See also * Orientin, the 8-C glucoside of luteolin.
