چکیده

امروزه استفاده از گیاهان دارویی به دلیل کاهش اثرات و عوارض جانبی مورد توجه پژوهشگران قرار گرفته است. گیاه اسپند از دیرباز برای ضدعفونی کردن رواج داشته است. این مطالعه به هدف بررسی اثر نانوذرات نقره بر قدرت ضد میکروبی گیاه اسپند روی باکتری اشریشیاکلای صورت گرفته است. ابتدا نانوذرات نقره با روشی جدید و سبز تهیه و سپس برای تولید نانوکامپوزیت نقره/عصاره اسپند به کار گرفته شدند. فرایند آنتی باکتریال با استفاده از روش دیسک گذاری دیفیوژن بر محیط کشت مولرهینتون صورت گرفت. با توجه به هاله‌ی عدم رشد اطراف دیسک‌ها که بیانگر اثرات آنتاگونیستی نانوذرات نقره و عصاره الکی گیاه اسپند می‌باشد، قدرت ضد میکروبی نانوکامپوزیت حاصل در مقایسه با هر کدام از نانوذرات نقره و گیاه اسپند به طور جداگانه بیشتر است. با توجه به نتایج می‌توان از این ترکیب در ساخت مواد ضدعفونی کننده بهره برد.

چکیده [English]

Today, the use of medicinal plants has been considered by the researchers due to the reduction of side effects. Syrian rue has long been used to disinfect. The aim of this study was to investigate the effect of silver nanoparticles on the antimicrobial activity of Syrian rue against E. coli. First, silver nanoparticles were prepared by a new green method and then used to produce silver nanoparticles/Syrian rue extract composite. Antibacterial process was performed using diffusion method on Mullerinton medium. Due to the lack of growth around the discs, which shows the antagonistic effects of silver nanoparticles and the extract of Syrian rue, the antimicrobial activity of the nanocomposite is higher than that of each of the silver nanoparticles and Syrian rue plant separately.
