Interpretive Summary: Essential oils from Turkish medicinal plants were obtained from the above ground parts from two Salvia species and evaluated for antimalarial, antimicrobial, and antifungal activity. One hundred and twenty-three phytochemicals were identified and 1,8-cinelole, borneol, and camphor were identified as the most abundant compounds. Antifungal activity against strawberry anthracnose pathogens (Colletotrichum species) was attributed to minor unidentified compounds in the oils. No antimicrobial activity to human pathogens was detected. Further studies will focus on identifying the components that possess activity against important agricultural plant pathogens.

Technical Abstract: Essential oils of Salvia macrochlamys and S. recognita were obtained by hydrodistillation of dried aerial parts and characterized by gas chromatography and gas chromatography – mass spectrometry. One hundred and twenty-three identified constituents representing 97.7% in S. macrochlamys and 96.4% in S. recognita were characterized and 1,8-cineole, borneol and camphor were identified as major components of the essential oils. The oils were evaluated for their antimalarial, antimicrobial and antifungal activities. Antifungal activity of the essential oils from both Salvia species was non-selective at inhibiting growth and development of reproductive stroma of the plant pathogens Colletotrichum acutatum, C. fragariae, and C. gloeosporioides. S. macrochlamys oil had good antimycobacterial activity against Mycobacterium intracellulare however, the oils showed no antimicrobial activity against human pathogenic bacteria or fungi up to a concentration of 200 µg/mL. S. recognita oil exhibited a weak antimalarial activity against Plasmodium falciparum.
