چکیده مقدمه: گزنه با نام علمی .Urtica dioica L علفی چندساله متعلق به خانواده گزنه است که اثر آللوپاتیک بالایی دارد. بسیاری از مواد شیمیایی که خصوصیات آللوپاتیک دارند، جوانه زنی را بیشتر از سایر مراحل نمو و استقرار گیاهچه تحت تاثیر قرار میدهند. گندم (.Triticum aestivum L) در طیف وسیعی از شرایط آب و هوایی رشد می کند و به مواد آللوپاتیک حساس است. این پژوهش به بررسی اثر عصاره گزنه بر خصوصیات جوا...
The present paper investigated the efficiency of Urtica dioica (U. dioica) on hemostatic and wound healing activities. U. dioica leaf extracts were evaluated for their antibacterial and antioxidant effects as well as their flavonoid and polyphenol content. The hydroethanolic extract (EtOH-H2OE), showing the most potent antibacterial and antioxidant activities in vitro, thanks to its flavonoid a...
استفاده از آنتیاکسیدانهای مصنوعی برای محافظت از روغن در برابر فساد اکسیداتیو، به علت سرطانزا بودن آنها محدود شدهاست. مطالعات برای استفاده از آنتیاکسیدانهای طبیعی به عنوان جایگزینی برای آنتیاکسیدانهای مصنوعی از اهمیت ویژهای برخوردار میباشد. هدف از این مطالعه بررسی تاثیر عصاره برگ گزنه (Urtica dioica) بر پایداری اکسیداتیو روغن کلزا و مقایسه آن در دو سطح 100 و 800 پی پی ام با آنتیاکس...

background and objective: nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. medicinal plants are also of great importance as antibacterial agents. therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of net...
This study was aimed to determine the changes of the local anchovy meal which is known as hamsi kaygana in Turkey during cold storage at +4°C ± 1°C. Physicochemical (pH, TVB-N, TMA-N, and TBA) shelf life analyses were carried out for hamsi kaygana samples. It was confirmed that the pH values obtained from research groups were within the limit values of the literature. No statistically significa...
Choline acetyltransferase was demonstrated in nettles (Urtica dioica), peas (Pisum sativum), spinach (Spinacia oleracea), sunflower (Helianthus annuus) and blue--green algae by using a Sepharose--CoASH affinity column. The column effected a 1500-fold purification of the enzyme from nettle homogenates and was required for demonstrating activity in the other higher plants. Demonstration of the en...
