The main aroma compounds of rosemary essential oil were found as 1,8-cineole and camphor. Trolox equivalent antioxidant capacity (TEAC) values for essential oils extracted by MAHD and HD were 1.52 mM/ml oil and 1.95 mM/ml oil, respectively. DPPH radical scavenging activity of the oils obtained by MAHD and HD were found as 60.55% and 51.04% respectively. Inhibitory effects of essential oils obtained by two methods on linoleic acid peroxidation were almost the same. Essential oils obtained by two methods inhibited growth of Esherichia coli O157:H7, Salmonella typhimurium NRRLE 4463 and Listeria monocytogenes Scott A with the same degree. However, inhibitory activity of essential oil obtained by MAHD on Staphylococcus aureus 6538P was stronger than that of obtained by HD (p < 0.05).EnglishROSMARINUS-OFFICINALIS L.2-DIMENSIONAL GAS-CHROMATOGRAPHYCONVENTIONAL HYDRO-DISTILLATIONVOLATILE SECONDARY METABOLITESCHEMICAL-COMPOSITIONANTIMICROBIAL ACTIVITYANTIOXIDANT PROPERTIESDIFFERENT EXTRACTIONMASS-SPECTROMETRYLAURUS-NOBILISArticle
