Abstract

Abstract: The aim of this study was to investigate the essential oil profile of Salvia thomasii (Southern Italy) and to assess the relationship of this taxonomic unit to S. fruticosa . The essential oil, obtained by hydrodistillation, was analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The main components are β-pinene, viridiflorol, 1, 8-cineole, camphor, α-pinene and trans -caryophyllene. The oil was tested for its potential antioxidant activity using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), Ferric Reducing Ability Power (FRAP) and β-carotene bleaching test. Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activity assays were used to screen the neuroprotective effect of the essential oil. A clear distinction of the two taxonomic units emerge by the comparison of S. thomasii and S. fruticosa s.l. essential oil composition. Considering the weak morphological differences and the clear-cut geographic separation we propose to treat the Italian unit at subspecies level as Salvia fruticosa Mill subsp. thomasii (Lacaita) Brullo, Guglielmo, Pavone & Terrasi.
