چکیده مقاله :
گیاهان منبع غنی از ترکیبات فنولی هستند که مهم ترین آنتی اکسیدان های طبیعی به شمار می آیند. اخیراً مطالعات متعددی روی منابع طبیعی به‌منظور یافتن منابع غنی از آنتی اکسیدان ها و نقش مصرف این ترکیبات در محافظت بدن در برابر صدمات ناشی از استرس اکسیداتیو انجام شده است. این تحقیق به منظور بررسی کمی و کیفی ترکیبات فنولی و فعالیت آنتی اکسیدانی عصاره متانولی پوست انار واریته رباب به عنوان جایگزین آنتی اکسیدان های سنتزی انجام شده است. در این مطالعه، ترکیبات ترکیبات فلاونوئیدی، آنتوسیانیدی و قدرت احیاء کنندگی اندازه گیری شد. در نهایت فعالیت آنتی اکسیدانی عصاره گیاه در غلظت های مختلف با استفاده از روش مهار رادیکال DPPH اندازه گیری گردید. نتایج به‌دست آمده نشان دادند که میزان ترکیبات فنولی، فلاونوئیدی و آنتوسیانیدی موجود در عصاره پوست انار به ترتیب mgTAE/gr83/70، mg CE/gr 33/21 و mMOL/100mL 66/136 می باشد. مطالعه اثر آنتی‌اکسیدانی نشان داد که عصاره متانولی پوست انار (mg/kg 600)، اکسیداسیون لینولئیک اسید را به میزان 61/89 درصد مهار می‌نماید. با افزایش غلظت ترکیبات فنولی عصاره ویژگی ضد رادیکالی آن افزایش پیدا کرده و همبستگی معنی داری بین ویژگی ضد رادیکالی و قدرت احیاء کنندگی عصاره متانولی پوست انار وجود دارد. نتایج نشان داد عصاره متانولی پوست انار سرشار از ترکیبات فنولی بوده و خاصیت آنتی اکسیدانی بالایی دارد. بنابراین می توان از این منبع گیاهی حاوی ترکیبات آنتی اکسیدان به عنوان نگهدارنده در صنایع غذایی استفاده کرد
Plants are riched by phenolic compounds and considered as the main natural antioxidants. Many efforts have been recently made to clarify the source of natural antioxidants and their roles to protect from oxidative stress injuries. The present study was aimed to qualify the phenolic compounds of pomegranate peel extract (PPE) of Rabbab variety and their antioxidant effect to substitute the synthetic compounds. Folin- Ciocalteu method was employed to investigate phenolic compound, while, spectrophotometery is used to measure flavonoid, antocyanin and oxidative ability. The antioxidant activity of different concentration of PPE was measured using DPPH. Results showed the concentrations of 70.83 mg TAE/g, 21.33 mg CE/g and 136.66 mmol/100 mL corresponding to the phenolic, flavonoid and antocyanin compounds, respectively. The antioxidant effect by linoleic system has shown to inhibit 89.61% of linoleic oxidation in the methanolic extract of PPE. Increasing the concentration of phenolic compound was simultaneous to raise its effect and a significant correlation between the antiradical activity and its reduction ability in the methanolic extract. The current results revealed the antioxidant activity of methanolic extract of Rabbab variety PPE and thus are recommended to apply in food industries.
