Özet

In European folk medicine, Salvia species have traditionally been used to enhance memory. In our previous study of 55 Salvia taxa, we explored significant anticholinesterase activity of cultivated S. fruticosa. In this study, we compared the inhibitory activity of dichloromethane, ethyl acetate, and ethanol extracts of 3 wild-grown samples and 1 cultivated sample of S. fruticosa against acetylcholinesterase and butyrylcholinesterase enzymes (which are associated with pathogenesis of Alzheimer's disease) by using the spectrophotometric Ellman method. Antioxidant activities were assessed by determining 2,2-diphenyl-1-picrylhydrazyl radical-scavenging activity, iron-chelating capacity, and ferric-reducing antioxidant power. The dichloromethane extract of the cultivated sample was then subjected to fractionation by using open column chromatography and medium-pressure liquid chromatography to obtain the most active fraction by activity-guided fractionation. All fractions and subfractions were tested in the same manner, and inactive subfractions were discarded. The essential oil of the cultivated sample was analyzed by gas chromatography-mass spectrometry.
