Hippomarathrum microcarpum grows wild in eastern Anatolia, Turkey, and is a plant utilized as foodby people. In this study, the in vitro antimicrobial and antioxidant activities of the essential oil andmethanol extract from H. microcarpum and its essential oil composition were investigated. Theessential oil, which has bornyl acetate, caryophyllene oxide, and 
-caryophyllene as its maincomponents, exhibited activity against eight bacteria, nine fungi, and a yeast, Candida albicans, withminimum inhibitory concentration values ranging from 62.50 to 125 
L/mL; the methanol extractshowed weak activity. The antioxidant activity of these extracts was assessed by the -carotenebleaching test and the 1,1'-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging test. The inhibitionof linoleic acid oxidation was very weak for both extracts tested. The inhibition percentages werefound to be 22.9 and 33.5% for methanol and essential oil, respectively, at the concentration of 2g/L. The oil scavenged DPPH at higher concentrations (IC50 = 10.69 ± 0.05 mg/mL), but the methanolextract exhibited no activity. The total phenolic content of the methanol extract was found to be4.7 ± 0.1%.
