Chemical Composition and Antifungal Activity of Salvia macrochlamys and Salvia recognita Essential Oils

Abstract

Essential oils of Salvia macrochlamys and Salvia recognita were obtained by hydrodistillation of dried aerial parts and characterized by gas chromatography and gas chromatography-mass spectrometry. One hundred and twenty 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 nonselective at inhibiting growth and development of reproductive stroma of the plant pathogens Colletotrichum acutatum, Colletotrichum fragariae, and Colletotrichum 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 microg/mL. S. recognita oil exhibited a weak antimalarial activity against Plasmodium falciparum.

“…In our previous paper (9) we reported that 1,8-cineole and α−pinene were also the most abundant constituents in the oil of endemic plant species S. brachyodon. Similar results were obtained with S. caespitosa (10), S.macrochlamys, S.recognita (11), S. cryptantha (12), S. clevelandii (13), S. aytachii (14), S. willeana, S. fruticosa and S. pomifera (15) The oil of S. ringens var. baldacciana.…”
