Resumo(s)
not widely explored. The gastrointestinal environment can modify these compounds, resulting in new combinations
with different bioactivity. This study aimed to evaluate the effects of simulated gastrointestinal digestion
(SGD) on rose and nasturtium flower extracts. Using UPLC-HRMS, 38 phenolic compounds were identified, and
the SGD caused significant changes, mainly in the glycosylated phenolic. Furthermore, antioxidant activity was
correlated with the increase in the concentrations of some polyphenols. Tested Gram-negative bacteria showed
sensitivity to the flower extracts; their growth was inhibited by up to 82.7%. SGD interrupted the bacterial
growth inhibition power of the rose extracts. On the other hand, an increase in inhibition ranging from 52.25 to
54.72% was found for nasturtium extracts, correlated to the behavior of some bioactive. Hence, SGD resulted in
significant changes in phenolic profiles of the edible flowers, increasing antioxidant activity and changing
antimicrobial effects.
