Eriodictyol 7-O-glucoside is a flavanone glucoside that has been found in V. coloratum and has diverse biological activities.1,2,3 It scavenges hydroxyl and superoxide anion radicals in cell-free assays (IC50s = 0.28 and 0.3 mM, respectively).1 Eriodictyol 7-O-glucoside activates nuclear factor E2-related factor 2 (Nrf2) in a reporter assay.2 It protects against cytotoxicity induced by cisplatin in human renal mesangial cells (HRMCs), but not A549 lung or MDA-MB-231 breast cancer cells, when used at a concentration of 80 ?M. Eriodictyol 7-O-glucoside (30 mg/kg) attenuates neurological deficits and reduces infarct volume in a rat model of cerebral ischemia induced by middle cerebral artery occlusion (MCAO).3
