ملخص المقالة :

با توجه به زیان‌های حاصل از مصرف آنتی‌اکسیدان‌های مصنوعی در صنایع غذایی، مطالعه و پژوهش برای یافتن جایگزین‌های طبیعی و سالم افزایش یافته است. در مطالعه حاضر، میزان ترکیبات فنولی و آنتی‌اکسیدان‌های موجود در پوست خرمالو مورد بررسی قرار گرفت. برای این منظور از حلال‌های اتانول و متانول با نسبت اختلاط 1 واحد پوست و 5 واحد حلال و به روش خیساندن برای استخراج عصاره استفاده گردید. سپس مقدار ترکیبات فنولی تام و ظرفیت آنتی اکسیدانی عصاره ها اندازه گیری شد. نتایج نشان داد که عصاره‌های اتانولی و متانولی به ترتیب دارای 6/255 و 15/241 میلی‌گرم گالیک اسید به ازای 100 گرم پوست تازه میوه بودند. همچنین عصاره اتانولی نسبت به عصاره متانولی از قدرت آنتی‌اکسیدانی بالاتری برخوردار بود.
