Chemical constituents and antimicrobial activities of Petroleum ether and n-butanol extracts from Linaria tingitana Boiss. & Reut.

In continuation of our phytochemical studies on the genus Linaria (Scrophulariaceae), we have investigated the petroleum ether (PE) and n-butanol (n-BuOH) extracts from the aerial parts of Linaria tingitana Boiss. & Reut. In this paper we describe the determination of nine methyl esters in the petroleum ether by GC-MS and the LC-MS profile of the n-BuOH extract together with the antimicrobial activity (Escherichia coli, Staphylococcus aureus, Bacillus sp., Alternaria sp. and Yarrowia sp.), both extracts exhibits antibacterial activity against Staphylococcus aureus and Bacillus sp., while no effects were observed about the antifungal activity. These results are reported for the first time for the spice
