molecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
Olive mill wastewater treatment using a simple zeolite-based low-cost method.
Olive mill wastewater (OMW), a liquid by-product of the olive oil industry, represents a severe environmental problem owing to its high pollution load. In this study, successive columns containing different types of natural materials were investigated for their OMW treatment efficiency. Passing OMW through three columns of gravel, fine sand, and a mixture of acidified cotton and zeolite (weight...
متن کاملSupercritical Antisolvent Micronization of Minocycline Hydrochloride
Micronization of minocycline hydrochloride dissolved in ethanol and with supercritical carbon dioxide as antisolvent was successfully performed using a recently built SAS apparatus. Amorphous particles of minocycline ranging from 100 to 1000 nm (depending on the operating conditions) were obtained. The mean particle size and the particle size distribution were determined by Dynamic Light Scatte...
متن کاملNucleophilic displacement reactions of 5′-derivatised nucleosides in a vibration ball mill
Vibration ball-milling in a zirconia-lined vessel afforded clean and quantitative nucleophilic displacement reactions between 4-methoxybenzylthiolate salts and nucleoside 5'-halides or 5'-tosylates in five to 60 minutes. Under these conditions, commonly-encountered nucleoside cyclisation byproducts (especially of purine nucleosides) were not observed. Liquid-assisted grinding of the same 5'-iod...
متن کاملCyclodextrins Micronization by Supercritical Assisted Atomization
Supercritical Assisted Atomization (SAA) has been used to micronize α-cyclodextrin (α-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD). The effect of some process parameters such as precipitation temperature and solute concentration in the liquid solution has been studied to evaluate their influence on morphology and size of precipitated particles. Cyclodextrins micronization has been obtained wi...
