چکیده | ||
چکیده در دهههای گذشته مطالعات فراوانی در زمینه تاثیر انواع امواج مغناطیسی بر موجودات زنده انجام شده است. ترکیبات فنلی یکی بزرگترین گروه ازمتابولیت های ثانویه هستند که در گیاهان انتشار گستردهای دارند و فعالیت بیولوژیکی و فارماکولوژی متنوع این ترکیبات در بسیاری از تحقیقات گزارش شده است. در این مطالعه میوه بامیه به منظور قرار گرفتن در معرض میدان مغناطیسی مرتب شدند. نمونهها در سه تکرار، سه زمان (3، 6، 9 دقیقه) و سه میدان (2/0، 4/0، 6/0 میلی تسلا) مورد آزمایش قرار گرفتند. به منظور اندازه گیری فنل و فلاونوئید کل، 5/0 گرم از هر نمونه کالوس تر با 5 میلی لیتر متانول 80 درصد (نسبت 1 به 10) در یک هاون سرد کوبیده و همگن شدند. مواد پس از یکنواخت سازی به مدت 24 ساعت در تاریکی و روی شیکر قرار داده و بعد از آن به مدت 5 دقیقه در 3000 دور در دقیقه سانتریفیوژ شدند. نتیجه چنین حاصل شد که میدان مغناطیسی اثرات متفاوتی بر میزان این دو خاصیت کیفی دارد. در مقایسه با تیمار شاهد، با افزایش میدان مغناطیسی، میزان فنل از 759/2 تا mgGUEg-1 932/2 افزایش معنی داری نشان داد درحالیکه محتوای فلاونوئید بهطور معنیداری از مقدار 821/0 به mgGUE g-10895/0 کاهش پیدا کرد | ||
