Abstract:
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,
Avalanche
presented values
for interna
l 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 cult
ivar
presented the minor Euclidean distance. The petals of the evaluated roses are excellent
sources of nutritional compounds and antioxidants.
