Nutritional Characterization, Bioactive Compounds and Antioxidant Activity of Brazilian Roses (Rosa spp)

The aim of this study was to evaluate thirteen cultivars of roses for nutritional composition, bioactive compounds and total antioxidant activity. Attaché cultivar had the highest amounts of proteins and total fiber. Regarding color,Avalanchepresented values for internal cromacity around ۷ fold higher than Attaché cultivar. The results showed that the evaluated roses presented means of bioactive compounds as ascorbic acid (۷۰.۴۷ mg ۱۰۰ g-۱), yellow flavonoids (۳۵.۲۵ mg ۱۰۰ g-۱) and total anthocyanins (۱۵۰.۴۰ mg ۱۰۰ g-۱).  The evaluated roses presented relatively low content of total carotenoids (۱.۲۵ mg ۱۰۰ g-۱), and high content of total polyphenols (۱۵۶۵ mg ۱۰۰ g-۱) and antioxidant capacity (۲۶۰ µM trolox g-۱). Avalanche, Prima Donna, Dolce Vita, Salmone, and Elisa cultivar presented the minor Euclidean distance. The petals of the evaluated roses are excellent sources of nutritional compounds and antioxidants.
