The oils obtained by hydrodistillation and steam distillation of the aerial parts of Stachys persica Gmel. and Stachys byzantina C. Koch grown in Iran were analyzed by GC/MS. The essential oil obtained by hydrodistillation of the aerial parts of S. persica was characterized by a high amount of non-terpenoid components of which methyllinoleate (27.7%), hexadecanoic acid (9.8%) and 6,10,14-trimet...

The volatile oil compositions of five Stachys species (Stachys officinalis L., St. grandiflora Host., St. byzantina Koch., St. germanica L. and St. sylvatica L.) have been studied using a GC/MS technique. All species gave low yields of oil. From St. officinalis 38 compounds were separated and partly identified, from St. grandiflora 24, St. byzantina 30, St. germanica 29 and St. sylvatica 43. Al...

From the aerial parts of Stachys byzanthina C. Koch., a new flavone glycoside, was isolated for the first time in addition to known two flavone glycosides. Structures were established by conventional methods of analysis and confirmed by H, C NMR and mass spectral analysis. Antiproliferative activities of isolated compounds, crude extract and fractions, fatty acids (extracts of hexane and hexane...

Background and Aims: Stachys L. species, which are members of the Lamiaceae family, have long been applied for their therapeutic benefits especially to cure cough, infection, genital tumors, ulcers, inflammatory illnesses, wounds in Anatolian traditional medicine. In current study, various extracts prepared from aerial parts cretica subsp. bulgarica Rech.f. (SC), byzantina K. Koch (SB), thirkei...

Abstract Iridoids are a class of secondary metabolites found in wide variety plants. typically plants as glycosides, most often to glucose. The genus Stachys L. is one the largest genera Lamiaceae family, containing iridoids. Aim aim this study was isolation and identification iridoids from aerial parts byzantina K. Koch germanica Methods For iridoids, different chromatographic methods (NP-TLC,...

The plant-pollinator relationship is generally considered mutualistic. This relationship is less clear, however, when pollinators also cause tissue damage. Some Megachilidae bees collect plant material for nests from the plants they pollinate. In this study, we examined the relationship between Anthidium manicatum, the European wool-carder bee, and the source of its preferred nesting material -...
