چکیده مقاله :
مقدمه: رادیکال های آزاد، محصولات جانبی طبیعی سوخت و ساز بدن به شمار می روند که در حضور آنتی اکسیدان ها اثر این رادیکال های آزاد خنثی شده و آسیب های ناشی از آنها کمتر می شود. یکی از آنتی اکسیدان های طبیعی ریبوفلاوین می باشد که در بیشتر مواد گیاهی و حیوانی وجود دارد. مولکول ریبوفلاوین یک ماده حساس به نور نیز هست که از طریق واکنش فوتوشیمیایی باعث ایجاد تغییر شیمیایی در مولکول های مجاور می شود. خاصیت آنتی اکسیدانی ریبوفلاوین متاثر از تابش نور بوده و حساسیت آن به نور باعث بازده بیشتر خاصیت آنتی اکسیدانی آن می شود. مواد و روش ها: در این پژوهش چهار پارامتر مهم شامل دما، غلظت ریبوفلاوین، زمان و تابش دهی نور بر خاصیت آنتی اکسیدانی ریبوفلاوین مورد بررسی قرار گرفت. برای این منظور، فعالیت آنتی اکسیدانی ریبوفلاوین بر اساس فعالیت مهار رادیکال آزاد پایدار دی فنیل پیکریل هیدرازیل (DPPH) به وسیله دستگاه اسپکتروفوتومتر UV-Vis تعیین شد. یافته ها: فعالیت آنتی اکسیدان ریبوفلاوین با افزایش غلظت در گستره غلظتی 7/0-4/0 میلی مولار بیشتر شد. در حضور نور خورشید فعالیت آنتی اکسیدانی ریبوفلاوین به گونه ای است که رادیکال آزاد DPPH را به طور کامل مهار می کند. همچنین در گستره دمایی به کار رفته، با افزایش دما فعالیت آنتی اکسیدان در مهار رادیکال آزاد شدیدتر شده است. از نظر سینتیکی، واکنش مهار رادیکال آزاد DPPH با استفاده از معادله سینتیک مرتبه یک توصیف شد. نتیجه گیری: با توجه به مطالعه انجام شده ریبوفلاوین به عنوان یک ماده حساس نوری دارای خاصیت آنتی اکسیدانی قابل ملاحظه ای در مهار رادیکال آزاد DPPH در حضور نور خورشید می باشد.
Introduction: Free radicals are natural metabolic products that can cause some serious damages to living cells like molecular oxidation and genetic mutation. Antioxidants are natural or synthetic molecules which inhibit the living cell‘s oxidation caused by free radicals. One of the natural antioxidants is riboflavin, which is available in many plants and animal materials. Riboflavin molecule is a photosensitive material which through the photochemical reaction causes chemical changes in the adjacent molecules. The effect of antioxidant and photosensitizer properties. Materials and Methods: In this study, the effect of four important parameters including temperature, riboflavin concentration, time and light irradiation on the antioxidant properties of riboflavin were investigated. The antioxidant activity of the riboflavin was determined based on the scavenging DPPH free radical (2, 2-diphnyl-1-picrylhydrazyl) using UV-Vis spectrophotometer. Results: The antioxidant activity of riboflavin is increased by increasing the concentration in the range of 0.4-0.7 mM. In the presence of sunlight, the free radicals of DPPH were completely scavenged by the antioxidant activity of riboflavin. In the applied temperature range, by increasing the temperature, the antioxidants activity became more intense in the free radical scavenging. Regarding kinetic, the DPPH free radical scavenging reaction was described using the first-order kinetic equation. Conclusion: According to this study, riboflavin as a photosensitive materials has a significant antioxidant effect on free radical DPPH in the presence of sunlight.
