The total phenolic contents and the essential oil compositions of the previously unknown Stachys taxa
(Labiatae), including Stachys pinardii Boiss, Stachys cretica L. subsp. mersinaea (Boiss.) 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 α-curcumene (34.10%) for S. cretica,
cedrandiol (25.26%) and caryophyllene dioxide (22.15%) for S. pinardii, and (Z)-β-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.
