Tanacetum argenteum (Lam.) Willd. subsp. flabellifolium (Boiss. & Heldr.) Grierson of Asteraceae is an endemic species in Turkey. Hydrodistillation of aerial parts using a Clevenger apparatus yielded an essential oil, which was subsequently analyzed by gas chromatography-mass spectroscopy (GC-MS). alpha-Pinene (29%), (E)-sesquilavandulol (16%), and camphor (14%) were found as main constituents....

Leaf gas exchange characteristics of a desert annual (Triticum kotschyi [Boiss.] Bowden) and the wheat cultivar TAM W-101 (Triticum aestivum L. em Thell) were compared over a range of leaf water potentials from -0.50 to -2.9 megapascals. At an ambient [CO(2)] of 330 microliters per liter, T. kotschyi had higher conductance and CO(2) assimilation (A) at a given water potential than T. aestivum. ...

Dracocephalum kotschyi Boiss, a member of Labiatae family, is a native plant to Iran, which has been reported to have immunomodulatory, antihyperlipidemic and antispasmodic activities. The objective of this research was to study the antispasmodic and antidiarrhoeal activities of hydroalcoholic and hexane extracts of D. kotschyi in mice.

Colitis is an inflammatory disease of the intestine with unknown etiology involving multiple immune, genetic, and environmental factors. We were interested to examine the effect of total extract from Dracocephalum kotschyi (D. kotschyi) Boiss. on the experimental colitis. D. kotschyi hydroalcoholic extract (10, 20, and 40 mg/kg) or apigenin (5, 10, and 20 mg/kg) were administered orally 2 h pri...
