Rech., and Stachys aleurites Boiss. & Heldr., all endemic to Turkey, were studied. Their essential oil compositions were investigated by GC-MS. It was found that the main constituents were alpha-curcumene (34.10%)for S. cretica, cedrandiol (25.26%) and caryophyllene dioxide (22.15%) for S. pinardii, and (Z)-beta-caryophyllene (31.60%) for S. aleurites. The total phenolic contents, by the Folin-Ciocalteu colorimetric method, of the S. pinardii, S. cretica subsp. mersinaea, and S. aleurites methanolic extract were found to be 600.74+/-0.23, 1200.94+/-0.11, and 900.61+/-0.06 mg gallic acid equivalent (GAE)/100 g in dried herb, respectively.eninfo:eu-repo/semantics/closedAccessStachys pinardiiStachys cretica subsp mersinaeaStachys aleuritesvolatile constituentstotal phenolicsArticle42217217410.1007/s10600-006-0070-1Q4WOS:0002393816000122-s2.0-33748174986Q3
