Demirpolat A. Essential Oil Composition Analysis, Antimicrobial Activities, and Biosystematic Studies on Six Species of Salvia. Life (Basel) 2023; 13:life13030634. [PMID: 36983789 PMCID: PMC10054517 DOI: 10.3390/life13030634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 02/16/2023] [Accepted: 02/21/2023] [Indexed: 02/26/2023] Open
Abstract
The essential oil constituents, antimicrobial properties, and biosystematic characteristics (morphological, palynological, and anatomical features) of six Salvia species from different regions of Turkey were investigated qualitatively and quantitatively in this study. The chemical composition of the essential oils of dried aerial parts of Salvia species, i.e., S. absconditiflora, S. ceratophylla, S. multicaulis, S. verbenaca, S. viridis, and S. syriaca were analyzed by GC-MS. The main constituents of the six Salvia species studied were 1,8-cineol, caryophyllene oxide, spathulenol, and borneol in different ratios. The antimicrobial activity of the essential oil extracted from the aerial parts of species of the genus Salvia was tested by the disc diffusion method. The essential oils of Salvia species showed different antimicrobial activity against the studied microorganisms. The highest antimicrobial activity against E. coli was observed in S. multicaulis and the highest antimicrobial activity against K. pneumoniae was observed in S. verbenaca. The morphology of the stem, leaf, bract, and flower structures of the Salvia species were analyzed in this study. Anatomical investigations focused on the root, petiole, and stem in more detail. Our research has broadened the criteria of anatomical characters unique to the Salvia species. Under light microscopy, the pollen grains of the six species belonging to Salvia were isopolar and radially symmetrical. The properties of the essential oil constituents, antimicrobial properties, and biosystematic data obtained in this study contribute to the bioactive and biosystematic studies of Salvia species used for food, pharmaceutical, and cosmetic purposes.
