These
types of compounds have the ability to donate hydrogen or electrons
beyond their capacity to form stable radical intermediates. The TP contents in different parts ofM.flexuosapointed this palm tree as a rich
source of polyphenolic compounds. The FE extract presented the
highest amount of TPs (378.07±3.12 mg GAEq/100 g), followed by
LE (102.54±0.12 mg GAEq/100 g), whereas the TE presented the
lowest amount of TPs (86.89±3.15 mg GAEq/100 g). The TFs ranged
from 567.16±1.15 to 246.84±1.11, as milligrams quercetin/100 g
dried weight. Again the highest TF content was found in the fruits,
followed by the leaves (398.77±0.3 mg QUEREq/100 g) and the lowest
amount was found in the trunk (Table 1). The TP and TF content of some
other typical Amazonian palm trees previously reported had higher
values: tucumã (Astrocaryum acualeatumG. Mey.)
