Resumo(s)
The present study aimed to evaluate the nutritional and bioactive potential of four edible flowers (borage,
centaurea, camellia, and pansies). Significant differences were observed among the four. Water was the main
constituent (> 76%, fresh weight - fw). Linoleic and palmitic acids were the major fatty acids found in borage
and red and yellow pansies, while in camellia it was the arachidic acid. In white pansies, behenic and arachidic
acids were predominant. Concerning vitamin E, α-tocopherol was the major vitamer. Carotenoids values varied
between 5.8 and 181.4 mg β-carotene/100 g dry weight (dw) in centaurea and borage, respectively, being
particularly rich in lutein. Malic acid was the major organic acid, except in centaurea, where succinic acid was
predominant. Fructose, glucose and sucrose were detected in all flowers. These results can contribute to the
knowledge of these edible flowers and consequently increase their popularity among consumers and in the food
industry.
