ACHE and memory impairment: Other studies on plant extracts like Nepeta nuda, Indigofera sessiliflora, Dendropanax morbifera, Pinus densiflora, Dichrocephala integrifolia, Alnus rugosa, Salvia moorcroftiana, and Sanguisorba minor have similarly reported reduced AChE activity and enhanced cognitive function in SCO-induced memory impairment models [40,41,42,43,44,45,46,47].
