Luteolin 7-O-glucuronide is a flavonoid that has been found in S. chloroleuca and A. pilosa, and has diverse biological activities, including antioxidant, enzyme inhibitory, and anti-inflammatory properties.1,2,3 It scavenges DPPH radicals in a cell-free assay (IC50 = 80.6 μM).1 Luteolin 7-O-Glucuronide inhibits porcine α-amylase and yeast α-glucosidase in vitro (IC50s = 61.5 and 14.7 μM, respectively).3 It also inhibits rat aldose reductase in vitro (IC50 = 0.7 μM) and sorbitol accumulation in isolated rat lens by 91.8% when used at a concentration of 5 μg/ml.1 Luteolin 7-O-glucuronide inhibits LPS-induced cytokine release from RAW 264.7 macrophages in a dose-dependent manner.2
