Objective: The aim of this study is evaluation of the changes of phytochemical compound in aerial parts of the Lovage plants at different developmental stages as well as antioxidant activity. Methods: The plants were harvested from Hezar Mountain. After drying, essent...
مقدمه: ارس و پیرو2 از مهمترین سوزنی برگان بومی ایران هستند و به عنوان مقاومترین درختان به سرمای شدید و خشکی، جایگاه ویژهای در نواحی کوهستانی ایران دارند. هدف: در این پژوهش سعی شده است ویژگیهای کمی و کیفی مواد موثره و اسانس مخروطهای ماده آنها با یکدیگر مقایسه و بررسی شود. روش بررسی: جهت بررسی اسانس حاصل از مخروطهای ماده این دو گیاه توسط GC-MS مورد شناسایی قرار گرفت. نتایج: نتایج نشان د...
Background & Aim: The Lamiaceae family is one of the largest and most distinctive families of flowering plants, with about 220 genera and almost 4000 species worldwide. The genus Stachys is one of the largest representative genera of the Lamiaceae family and includes about 300 species, in the subtropical and tropical regions of both hemispheres. In Iran this genus is represented by 34 ...
Objective(s): Development of a nanobiosystem by using plant essential oils with green synthesized silver nanoparticles that present synergistic antibacterial activity for overcoming antibiotic resistance in pathogenic bacteria. Material and Methods: Essential oils (EOs) of Kelussia odoratissima and Teucrium polium extracted by hydrodistillation were analyzed by gas chromatography-mass spectrome...
Introduction & Aim: The aim of this study was evaluating effect of methanol and ethanol foliar application as a new and safe technology in plant production on lemon balm’s (Melissa officinalis L.) volatile oil components. Experimental: Experimental carried out based on a Randomized Complete Block Design (RCBD) with fifteen treatments and three replications in the experimental field of...
Fungi release wide spectrum of volatile organic compounds (VOCs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. Trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...

The members of the Inula candida / I. verbascifolia group are perennial and chasmophytic plants attributed to four species eleven entities at subspecific or varietal level. They mostly confined Greece. Volatile compounds above-ground flowering parts twenty-three populations covering ten taxonomic were obtained after hydrodistillation analyzed by gas chromatography mass spectrometry (GC-MS). In ...
در این تحقیق اثر عوامل محیطی برکمیت وکیفیت اسانس گونه teucrium chamaedrys مورد مطالعه قرار گرفت. نمونه برداری در اواسط خرداد ماه از سر شاخه های گلدار گونه مریم نخودی طناز انجام شد. بعد از خشک شدن نمونه ها در سایه، با روش تقطیر با آب طرح کلونجر اسانس گیری هنجام شد. و اجزای اسانس با روش کروماتوگرافی گازی متصل به طیف سنجی جرمی (gc/ms) شناسایی شد. همچنین نیتروژن، پتاسیم، فسفر، ماده آلی، اسیدیته، هد...
Based on the previously researches, this manuscript comprehensively analysed chemicals in essential oil (EO) from pericarp of Nanfengmiju, a variety Citrus kinokuni Hort. ex Tanaka. The isolated crystals EO were mainly composed series alkanes. In total, 33 alkanes identified, which 14 ones firstly reported peels EOs L., to best my knowledge. Previously, neglected and never thought as chemical m...
