Essential oils from the aerial parts of Frankenia laevis were obtained by steam distillation and were analyzed by GC-FID and GC/MS. Forty-four compounds were identified, representing 91.5% of the oil constituents. Hexadecanoic acid was the major compound (19.8%), followed by methyl linoleate (16%), (E, E)-farnesyl acetate (9.5%), (E)- nerolidol (8.9%) and benzyl benzoate (6.8%). Minimum inhibitory concentrations, minimum bactericidal concentrations and inhibition zone diameters against grain-positive bacteria, gram-negative bacteria and phytopathogenic fungi were determined. Essential oil was particularly effective against Staphylococcus aureus, Micrococcus luteus and Salmonella typhimurium, nevertheless no antifungal activity was detected at the tested concentrations. © 2010 Allured Business Media.

The petroleum ether, chloroformic, ethyl acetate and methanolic extracts of Limonium echioides L. (Plumbaginaceae) were screened for their antioxidant and antifungal activities through in vitro experiments. The 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS•+) decolorization and 1,1-diphenyl-2-picrylhydrazyl (DPPH•) free radical-scavenging method were used. All extracts were active with radical-scavenging capacity reaching 100% in DPPH• reaction system and 85.6% in ABTS•+ reaction at the used concentrations. Methanolic extract was found to possess the highest free radical-scavenging effects in both assays. An important correlation between antioxidant capacities and total phenolic contents of the polar extracts was found. The gallic acid, identified in this plant, seemed to be active against both radicals DPPH• and ABTS•+. The mycelium growth inhibition method was used for the antifungal testing. Ethyl acetate and methanolic extracts of L.echioides showed antifungal activities against Fusarium oxysporum and Penicillium sp. © 2012 Wiley Periodicals, Inc. Source
