the essential oil from flowering aerial parts of nepeta macrosiphon boiss. growing wild in kermanshah province, iran, was analyzed by gc/ms. this essential oil was prepared by a modified likens-nickerson’s simultaneous distillation-extraction (sde) method. forty-five compounds consisting 95.1% of the total components were identified from the oil obtained with a yield of 0.1%w/w. among them, spa...

The aim of this work was to determine the effects of two geographically different strains of Rhizophagus intraradices (M3 and GA5) on the total biomass and essential oil (EO) yield and composition of Calamintha nepeta, with or without phosphorus (P) fertilization, under greenhouse conditions. The plant biomass was not significantly affected by any of the treatments, showing higher values in con...

Nepeta satureioides Boiss. has been used in traditional medicine of eastern countries and is famous for its medicinal properties. The aim of this study was to evaluate the effect of methanol (MeOH), n-hexane and dichloromethane (CH2Cl2) fractions of the extract on melanin synthesis and oxidative stress in B16F10 melanoma cell line. The B16F10 cell line viability after treatment with increasing ...

Karyotypes of ten sections of genus Trigonella Linnaeus, 1753 (Fabaceae) from Turkey were investigated. Somatic chromosome numbers of examined species were determined as 2n=14 and 16. The karyotype analyses of the species were carried out and somatic chromosome numbers of Trigonella plicata Boiss., 1872, Trigonella brachycarpa (Fisch.) Moris, 1833, Trigonella rostrata Boiss., 1872, Trigonella l...

Isolation and GC/MS quantitative determination of ursolic acid in the herb of Nepeta cataria var. citriodora have been performed. The content of this compound was in the range 0.95 ñ 1.30%. Daucosterol (βsitosterol 3-O-β-D-glucoside) was also isolated from the plant, in addition to small amounts of β-sitosterol, campesterol, α-amyrin and β-amyrin. The content and composition of essential oil in...

In this study, we aimed to determine chemical composition and antibacterial activities of Satureja hortensis and Calamintha nepeta against to 20 phytopathogenic bacteria causing serious crop loss. The essential oils of S. hortensis and C. nepeta were isolated by the hydrodistillation method and the chemical composition of the essential oils were analyzed by GC-MS. The antibacterial properties o...
