detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
بررسی های ساختاری، اکسایشی-کاهشی و کاتالیستی نانوذرات a1-xa?xb1-yb?yo3 ( a or a? = sr, la and b or b? = mn, co, fe) برای اکسایش co به عنوان آلاینده هوا
در این پروژه، خواص ساختاری، اکسایشی-کاهشی و کاتالیستی نانو ذرات la1-xsrxmn0.5co0.5o3 با مقادیر x برابر 0/0، 1/0، 2/0، 3/0، 4/0، 5/0 و 75/0 و la1-xsrxfe0.5co0.5o3 با مقادیر x برابر 0/0، 15/0، 30/0، 45/0، 60/0 برای تبدیل co (آلودگی اگزوز خودروها) به co2 و آب بررسی شده اند. نانو کاتالیست ها به روش سیترات تهیه شدند. در این روش، یک محلول شامل تراکم های مناسب نمک های نیترات و اسید سیتریک، معادل با تع...
15 صفحه اولToxic Christmas and New Year Holiday Plants...or Are They?
Background: Poinsettia (Euphorbia pulcherrima), holly (Ilex opaca) and mistletoe (Phoradendron flavescens) adorn homes during the Christmas and New Year holiday season and create the potential for curious children to sample their colorful leaves and enticing berries. This study was aimed to review the American Association of Poison Control Centers National Poison Data System (AAPCC NPDS) to des...
متن کاملNew Platforms For Drug Screening And Toxicology: Necessity Or Need?
The liver is the largest internal organ in the human body that is responsible for more than 500 vital functions, including biosynthesis of major plasma proteins, immunity against infectious pathogens, balancing energy metabolism and xenobiotics biotransformation (1). One of the main functions of the liver is an important role in drug metabolism (2). Since developing new drug compounds into mark...
متن کاملSpacelike hypersurfaces with constant $S$ or $K$ in de Sitter space or anti-de Sitter space
Let $M^n$ be an $n(ngeq 3)$-dimensional complete connected and oriented spacelike hypersurface in a de Sitter space or an anti-de Sitter space, $S$ and $K$ be the squared norm of the second fundamental form and Gauss-Kronecker curvature of $M^n$. If $S$ or $K$ is constant, nonzero and $M^n$ has two distinct principal curvatures one of which is simple, we obtain some charact...
