Staphylococcus aureus antifungal activity against

Mandal et al. (68) have reported on the antimicrobial activity of the leaf extract of K suaveolens. The steam-distilled oil, petroleum ether and ethanol extracts exhibited broad-spectmm antibacterial and antifungal activity against Bacillus subtilis. Staphylococcus aureus, Escherichia coli. Pseudomonas aeruginosa and Micrococcus luteus., and the fungi Fusarium oxysporum. 

Kolanone (86), nemorosone II (89), propolone A (93), chamone 1 (119), and xanthochymol (138) displayed significant antimicrobial and antifungal activity against a variety of pathogenic yeasts and bacteria [72,74,77,120]. Compounds 131-134 and 138 displayed antibacterial activity against methicill in-resistant Staphylococcus aureus (MRSA) at 3.1 - 12.5 /(g/mL, nearly equal to the antibiotic vancomycin [89]. 

A significant antimicrobial activity against Staphylococcus aureus and Escherichia coli and antifungal activity on Aspergillus niger and Helminthosporium oryzae were also found for 2-(2-chloroethyl) and 2-allyl-2,3-dihydro-5-benzoyl-1/7-1,3,2-benzodiazaphosphole 2-oxides <2004CPB307>. 

Karamenderes et al. [67] reported the composition and antimicrobial activity of the essential oils obtained from Achillea millefolium L. subsp. pannonica (Scheele) Hayek, Achillea millefolium subsp. millefolium, Achillea arithmifolia Waldst Kitt and Achillea kotschyi Boiss. subsp. kotschyi, four Achillea species from Turkey. 1,8-cineole, Fig. (2), artemisia alcohol and ascaridole were identified as major components. The essential oils showed antibacterial and antifungal effects even with low concentrations. The essential oil of the flowering tops of another Achillea species, Achillea fragantissimum (Forsk.) Sch. Bip growing in Sinai, was analyzed [68]. Santolina alcohol, a- and P-thujone, Fig. (5) and artemisia ketone account for approximately 80% of the oil. The oil showed marked antimicrobial activities against Escherichia coli. Bacillus subtilis and Staphylococcus aureus.
