Four compounds were isolated from ethyl acetate and methanol extracts of the flowered aerial parts of Hymenocrater calycinus (Lamiaceae) using chromatographic methods and identified by spectroscopic data (MS, 1H- and 13C-NMR, HMQC, HMBC and 1H-1H COSY). Antifungal and antibacterial effects of rosmarinic acid, the main component, were determined against Staphylococcus aureus, Escherichia coli, Candida albicans and Aspergillus niger within the broth dilution method.

Isolated compounds were identified as β-sitosterol (1), ursolic acid (2), rosmarinic acid (3) and quercetin 3–0- rutinoside (4) for the first time in Hymenocrater genus. The results of our assay against bacteria and fungi represent that rosmarinic acid has an antifungal property against Candida albicans (MIC, 250µg/ml).
