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 7 fold higher than attaché cultivar. the results showed that the evaluated roses presented means of bioactive compounds as ascorbic acid (70.47 mg 100 g^-1), yellow flavonoids (35.25 mg 100 g^-1) and total anthocyanins (150.40 mg 100 g^-1).  the evaluated roses presented relatively low content of total carotenoids (1.25 mg 100 g^-1), and high content of total polyphenols (1565 mg 100 g^-1) and antioxidant capacity (260 µm trolox g^-1). 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.
