ChEBI: A dihydroxy- and monomethoxy-flavone in which the hydroxy groups are positioned at C-5 and C-7 and the methoxy group is at C-6. | [Biological Activity]
Oroxylin A is a flavonoid isolated from Scutellaria baicalensiswhich is one of the most important medicinal herbs in traditional Korean/Chinese/Japanese medicine. The amelioration of Abeta(25-35) peptide-induced memory impairment by oroxylin A is believed to be mediated via the GABAergic neurotransmitter system after a single administrationor by reductions in Abeta(25-35) peptide-induced astrocyte and microglia activationsiNOS expressionlipid peroxidationand increased cholinergic neurotransmission after subchronic administration. |
