Essential oil composition and antibacterial activities of Gypsophila species

Essential oil composition of Gypsophila turcica Hamzaoglu, Gypsophila pinifolia Boiss. & Hausskn., G . tuberculosa Hub.-Mor., G . eriocalyx Boiss. and G . laricina Schreb. were analyzed by means of gas chromatography-mass spectrometry (GC-MS). Thirty six, fourty four, sixty six, forty one and sixty one compounds were identified in the essential oils of G . turcica , G . pinifolia , G . laricina , G . tuberculosa and G . eriocalyx respectively. The major components were determined hentriacontane (12.93 ± 0.4%), 1-octadecanol (8.97 ± 0.1%), hexahydrofarnesyl acetone (6.9 ± 0.09%) and pentacosane (6.63 ± 0.08%) in G . turcica oil, hexadecanoic acid (17.6 ± 0.4%), 1-tetradecanol (7.6 ± 0.1%) and phytol (5.63 ± 0.05%) in G . pinifolia oil, octacosane (6.83%), eicosanal (6.19%), triacontane (6.03%) and heneicosane (5.78%) for G . eriocalyx , hexadecanoic acid (25.3%, 27.0%) and hentriacontane (13.0%, 12.6%) for G . tuberculosa and G . laricina , respectively. Antibacterial activity of G . eriocalyx , G . tuberculosis and G . laricina were investigated against Gram negative ( Escherichia coli ) and Gram positive ( Staphylococcus aureus ) bacteria.
