چکیده
مایکوتوکسین ها به عنوان مواد سرطان زا، تراتوژن، ژنوتوکسیک، هپاتوتوکسیک و نفروتوکسیک گزارش شده اند. بنا به مطالعات مروری انجام یافته، انجام مطالعات بیشتر به منظور تعیین آلودگی مایکوتوکسینی در همه انواع مواد غذایی وجود دارد. در مطالعه حاضر، 20 نمونه پودر سنجد به صورت تصادفی-خوشه ای و بر اساس پراکندگی محل های فروش از نواحی مختلف شهر اردبیل تهیه شد. تعیین آلودگی آفلاتوکسینی با استفاده از کروماتوگرافی مایع با کارآیی بالا و خالص سازی با ستون ایمونوافینیتی صورت گرفت. بنا به نتایج، هفده نمونه از کل نمونه ها (85 درصد) آلودگی آفلاتوکسینی با دامنه 0/2360-40/30 میکروگرم در کیلوگرم داشتند. آفلاتوکسین های B1 و B2 در 85 درصد نمونه ها مشاهده شد. آلودگی آفلاتوکسین های G1 و G2 به ترتیب در 80 و 70 درصد نمونه ها گزارش شد. سطح آلودگی افزون بر حداکثر مجاز ایران و اتحادیه اروپا بود. این یافته ها نیاز به پایش بیشتر آلودگی آفلاتوکسینی پودر سنجد و جمعیت مصرف کننده آن را در ایران نشان می دهد.

چکیده English

Mycotoxins have been reported to be carcinogenic, teratogenic, genotoxic, hepato- and nephrotoxic. Based on the literature review, there is a need for more studies on the mycotoxin contamination in all types of foods. In this study, 20 samples of Elaeagnus angustifolia L. powder were purchased randomly and clustered based on the distribution of sales areas from different districts in Ardabil city. The determination of aflatoxin contamination was carried out using high performance liquid chromatography and immunoaffinity column clean-up.

According to the results, seventeen of 20 samples (85%) were found contaminated with aflatoxins in the range of 30.40-2360.0 µg/kg. Both AFB1 and AFB2 were detected in 85% of samples. 80% and 70% samples had AFG1 and AFG2, respectively. The contamination levels were exceeded the maximum limit of Iran and European Union. These findings suggest an urgent need to monitor contamination of aflatoxin and consuming population of Elaeagnus angustifolia L. powder in Iran.
