Abstract :
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.
