در این پروژه ترکیبات شیمیایی اسانس ها، خواص آنتی اکسیدانی و آنتی میکروبی عصاره متانولی سه گونه استاکیس stachys setifera, stachys pilifera, stachys spectabilis اندازه گیری شد. تجزیه gc و gc/ms و اسانس های بدست آمده به دو روش تقطیر با آب و نانو لوله شناسایی و مقایسه شد.ترکیبات اصلی به روش تقطیر با آب برای سه گونه به ترتیب: stachys setifera : caryophyllene oxide(14.47%), piperitenone oxide(10.14%)...
پونه از جمله گیاهان بسیار مهم معطر و دارویی است که مصارف گستردهای در صنایع مختلف دارد. هدف از این بررسی شناسایی و کاربرد ترکیبهای اسانس پونه میباشد. نمونه کشت شده پونه کرمانی M. longifolia (L.) Hud. var. kermanansisو پونه جنگلی M. longifolia (L.) Hud. var. kotschianaدر ایستگاه البرز کرج در زمان گلدهی، برگ و گل برداشت گردید و با روش تقطیر با بخار آب تحت اسانسگیری قرار گرفت. جهت شناسایی ترکیبه...
A comprehensive study on essential oils (EOs) extracted from some Mentha suaveolens L. samples, collected in the countryside of Tarquinia, is reported. In this study, the procedure for essential oil preparation, in terms of harvesting and extraction time, was analyzed in detail for the first time. The GC/MS analysis, carried out on 18 samples, revealed that piperitenone oxide (PO), the main ess...

In vitro plantlets and callus of M. longifolia were established and their volatile constituents characterized by GC-MS analysis of their headspaces (HSs) and essential oils (EOs). Significant quali-quantitative differences were found in the aromatic fingerprints in comparison with the M. longifolia parent plants. In fact, limonene and carvone were the main constituents in the EOs of the mother ...
This work has demonstrated the ixodicidal and insect antifeedant effects of essential oils from 14 experimentally cultivated aromatic plants. The strong corresponded to Thymus zygis, vulgaris, Satureja montana, Oreganum virens , Mentha suaveolens . moderately active were Lavandula angustifolia, piperita, spicata, Artemisa herba-alba Rosmarinus officinalis most effective larvicidal compounds pip...
Abstract Clinopodium serpyllifolium is a perennial medicinal plant generally used as herbal tea in folk medicine. Leaves of C. from the representative exemplars Newe Ya’ar living germplasm collection were analyzed for their polyphenolic and volatiles composition, tested antioxidant activity. The oxygenated monoterpenes pulegone (10.4–50.6%), piperitenone oxide (3.2–28.6%), (0.9–14.6%), trans -p...
