Phytochemical analysis of Lavandula stoechas (L.)ensured the presence of phenolics, flavonoids, and tannins, and methanolic extract of the plant showed potent free-radical-scavenging activity with an IC50 value of 76.73 μg/mL, declined brain AChE and malondialdehyde levels, and improved glutathione (GSH), catalase, and superoxide dismutase (SOD) levels, suggesting attenuation of dementia in scopolamine-induced memory-deficit mice [23]. The gene discussed is ACHE; the disease is dementia.
