Chemical composition and antimicrobial activity of essential oils of Jasonia candicans and J. montana.

The essential oils of the aerial parts of Jasonia candicans and J. montana were analyzed by gas chromatography-mass spectrometry (GC/MS) technique. Of twenty-one components identified in the volatile oil of J. candicans, intermediol was the main constituent. Fifty-eight components were characterized in the essential oil of J. montana. Camphor, borneol, bornyl acetate, chrysanthemol, intermediol, and 1,8-cineole were the major constituents in this oil. The two oils showed antibacterial activity against Bacillus subtilis. They also showed a marked antifungal activity against Trichophyton mentagrophytes, Cryptococcus neoformans, and Candida albicans.
