چکیده مقاله :
گیاهان منابع ارزشمندی از ترکیبات آنتی‌اکسیدانی و ضدمیکروبی مختلف هستند. ترکیب و ساختار گروه‌های عاملی اسانس‌ها و عصاره‌ها نقش مهمی در فعالیت آنتی‌اکسیدانی و ضدمیکروبی آن‌ها ایفا می‌کنند. گیاه جغجغه یا کهورک (Prosopis farcta) از خانواده Leguminosea و زیر‌خانواده Mimosoideae است و بومی نواحی خشک و نیمه‌خشک آسیا، آفریقا و آمریکاست. در این پژوهش با استفاده از روش سوکسوله و حلال اتانول 70 درصد، عصاره ریشه گیاه کهورک تهیه و درصد بازده عصاره 1/85 درصد به‌دست آمد. فنل کل و ترکیبات فلاونوئیدی به‌ترتیب برابر با 0/17 ± 14/ 178 میلی‌گرم هم‌ارز اسید گالیک در گرم و 77/ 0± 94/33 میلی‌گرم هم‌ارز کوئرستین در گرم محاسبه شد. ترکیبات فنلی 98/11 درصد از کل ترکیبات شیمیایی عصاره را تشکیل داده بودند. مقدار 50IC برای عصاره اتانولی ریشه گیاه کهورک برابر 2/45 میکروگرم بر میلی‌لیتر و آنتی‌اکسیدان سنتزی BHT (نمونه کنترل)11/98 میکروگرم بر میلی‌لیتر به‌دست آمد. در سیستم بتاکاروتن-لینولئیک اسید، میانگین درصد فعالیت آنتی‌اکسیدانی 39/25 را برای عصاره ریشه کهورک و 13/57 درصد برای BHT تعیین شد. در بین غلظت‌های 250، 500 و ppm 1000، غلظت ppm 1000 عصاره بهترین اثر آنتی‌اکسیدانی را در روغن سویا طی 12 روز نگه‌داری در دمای 50 درجه سلسیوس داشت. استافیلوکوکوس اورئوس با MIC برابر 200 میکروگرم بر میلی‌لیتر و MBC برابر 350 میکروگرم بر میلی‌لیتر، نسبت به دو باکتری گرم منفی سالمونلا تیفی‌موریوم و اشریشیا کولای در برابر عصاره حساسیت بیشتری نشان داد. نتایج این پژوهش نشان داد که عصاره اتانولی-آبی ریشه کهورک از فعالیت ضدمیکروبی و آنتی‌اکسیدانی مناسبی برخوردار است.
چکیده انگلیسی:
Plants are valuable sources of different antioxidant and antimicrobial compounds. The composition and structure of the functional groups of essential oils and extracts play an important role in their antioxidant and antimicrobial activity. Prosopis farcta is a spice of Leguminosae family and Mimosoideae subfamily, an aborigine to the dry and semi-dried regions of Asia, Africa and America. In this study, the root extract of Prosopis farcta prepared by the soxhlet extractor and ethanol 70% solvent. The extraction yield was estimated at 1.85%. Total phenol and flavonoids compounds were calculated 178.14 ± 0.17 mg Gallic acid/g and 94.33 ± 0.77 mg Quercetin/g, respectively. Phenolic compounds comprised 11.98% of the total chemical composition of the extract. IC50 for root extract and BHT (synthetic antioxidant) was determined 2.45 μg/ml and 1.98 μg/ml, respectively. In the β-carotene-linoleic acid system, the average antioxidant activity reported 39.25% for root extract and 57.13% for the BHT. Among 250, 500 and 1000 ppm concentrations of the extract, 1000 ppm showed the best antioxidant effect in soybean oil for 12 days storage at 50°C. Staphylococcus aureus (with MIC 200 µg/ml and MBC 350 µg/ml) showed the most sensitivity in comparison with the two gram-negative bacteria, Salmonella Typhimurium and Escherichia coli. The results of this study showed that the hydro-ethanolic root extract of Prosopis farcta had suitable antimicrobial and antioxidant activity.
