چکیده مقاله :
گل کاغذی (spp.Bougainvillea ) به عنوان یک گیاه زینتی، دارویی و خوراکی شناخته شده است اما در پژوهش‌های پیشین به خوراکی بودن ارقام مختلف گل کاغذی کمتر پرداخته شده است. در این پژوهش 4 رقم گل کاغذی (B. glabra, B. glabra "Snow White", B. specabilis "Scarlett OHara", B. buttiana "Louis Wathen) به جهت مصارف خوراکی بررسی شدند. گل‌های کاغذی در مرحله گل کاملا باز از یک تولید کننده تجاری در استان گیلان-شهرستان تالش خریداری و از گلبرگ‌ها جهت تعیین درصد مواد معدنی، ویتامین C، آنتوسیانین گلبرگ و ظرفیت آنتی‌اکسیدانی استفاده شد. نتایج نشان داد که B. specabilis "Scarlett OHara" دارای بالاترین سطح فسفر (32.10 mg/100 g F.W.)، کلسیم (98 mg/100 g F.W.)، آهن (3.79 mg/100 g F.W.) و آنتوسیانین (31.14 mg/100 g F.W.) است. بیشترین مقدار پتاسیم به‌ترتیب با 81/181 و 52/181 میلیگرم در 100 گرم وزن تر برای B. glabra و "Scarlett OHara" B. specabilis و بیشترین مقدار روی (0.35 mg/100 g F.W.) برای B. glabra ثبت شد. "Snow White" B. glabra ضعیف ترین منبع از نظر روی، آهن، فسفر و آنتوسیانین بود. "Snow White" B. glabra و "Louis Wathen" buttiana B. بهترین ارقام از نظر ویتامین C و"Snow White" B. glabra و B. glabra نیز بهترین ارقام گل کاغذی از نظر ظرفیت آنتی‌اکسیدانی بودند. در کل مشخص شد که هر چهار رقم گل کاغذی دارای ارزش غذایی هستند اما با توجه به اینکه "Scarlett OHara"B. specabilis از نظر مواد معدنی و "Snow White"B. glabra از نظر ویتامین C و ظرفیت آنتی‌اکسیدانی نسبت به سایر ارقام برتری داشتند به‌عنوان بهترین ارقام جهت مصرف توصیه می‌شوند.
The Bougainvillea spp. is an ornamental, medicinal, and edible flower whose edibility has been less addressed in previous studies. This research explored the edible application of four paper flower cultivars (B. glabra, B. glabra ‘Snow White’, B. glabra ‘Scarlett O’Hara’, and B. glabra ‘Louis Wathen’). The paper flowers were purchased at the full blooming stage from a commercial producer in Talesh County, Guilan province, and their petals were used to determine the contents of minerals, vitamin C, anthocyanin, and antioxidant activity. The results showed that B. glabra ‘Scarlett O’Hara’ had the highest P (32.10 mg/100 g FW), Ca (98 mg/100 g FW), Fe (3.79 mg/100 g FW), and anthocyanin content (31.14 mg/100 g FW). The highest K contents (181.81 and 181.52 mg/100 g FW) were obtained from B. glabra and B. glabra ‘Scarlett O’Hara’, and the highest Zn content (0.35 mg/100 g FW) was recorded by B. glabra. Also, B. glabra ‘Snow White’ was the weakest in Zn, Fe, P, and anthocyanin contents. B. glabra ‘Snow White’ and B. glabra ‘Louis Wathen’ were the best in vitamin C content, and B. glabra ‘Snow White’ and B. glabra were the best in antioxidant capacity. In general, it was found that all four cultivars had nutritional value. However, the best were B. glabra ‘Scarlett O’Hara’ due to its mineral content and B. glabra ‘Snow White’ due to its vitamin C content and antioxidant capacity.
