Chemical compound

Oroxylin A is anO-methylated flavone, a chemical compound that can be found in the medicinal plantsScutellaria baicalensis^[1] andScutellaria lateriflora,^[2]^[3] and theOroxylum indicum tree.^[4] It has demonstrated activity as adopamine reuptake inhibitor,^[5] and is also anegative allosteric modulator of thebenzodiazepine site of theGABA_A receptor.^[5]^[6]^[7] Oroxylin A has been found to improvememory consolidation in mice by elevatingbrain-derived neurotrophic factor (BDNF) levels in thehippocampus.^[8]
