Biochem/physiol Actions

Oroxylin A is a flavonoid isolated from Scutellaria baicalensis, which 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 administration, or by reductions in Abeta(25-35) peptide-induced astrocyte and microglia activations, iNOS expression, lipid peroxidation, and increased cholinergic neurotransmission after subchronic administration.
