طالبی در سطح وسیعی در ایران کشت می گردد ولی عملکرد آن در هکتار پایین است. به منظور افزایش عملکرد دو آزمایش تحت تاثیر کاربرد جیبرلیک اسید در مرحله جوانه زنی (آزمایشگاه) و همچنین جیبرلیک و هیومیک اسید در مرحله رویشی و زایشی (مزرعه) در گیاه طالبی رقم سمسوری انجام گرفت. درآزمایش جوانه زنی، بذرها در غلظت های 0، 200، 400، 600 میلی گرم در لیتر به مدت 24 ساعت خیسانده و سپس در پتری دیش قرار داده شدند. ت...
a new model is proposed in this research to calculate the longitudinal strengthof unidirectional e-glass reinforced polymer composites exposed to sulfuricacid environment, using a micromechanics model. in the proposed method,it is assumed that the residual strength of the degraded composites under acidic environment can be calculated by knowing the degraded strength properties of the constituen...
plants of asteraceae are used in traditional medicine and phytotherapy. the two main caffeic acid derivatives, chicoric and caftaric acid which are found in many genus of asteraceae including echinacea exhibit important biological activities. the level of these acids in e. purpurea is affected by many factors such as growing situations, extraction methods, storage conditions and plant age. in t...

در این مطالعه، برای اولین بار بررسی فیتوشیمیایی گیاه alyssum maritimum انجام شد. اسانس گل این گیاه با استفاده از تقطیر ساده نوع کلونجر استخراج و با دستگاه gc/ms آنالیز شد. آنالیز دستگاهی 32 ترکیب که 246/99 %کل اسانس بود را نشان داد. مهمترین ترکیبات اسانس این گونه: 3-butenyl isothiocyanate با 205/85 درصد، naphtho[1,2-c]furan-3(1h)-one با 059/3 درصد، 2-thiazolecarboxylic acid, 4-methyl-, ethyl e...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
introduction: bread made from wheat flour is an important source of minerals such as iron and zinc, but its phytic acid content is a contributing factor that can cause decreased absorption of these minerals. this survey aimed to determine phytic acid content in different types of bread and dough consumed in yazd, iran. materials and methods: a descriptive, cross-sectional study was carried ou...
