In
the
optimized
extract
(unfiltered)
two
phenolic
acids
and
one catechin were identified and quantified (Table 4). Among
he phenolic acids, chlorogenic acid (5-caffeoylquinic acid)
howed the highest concentration, which is in accordance to
hat
reported
by
Filip
et
al.
(2001),
Cardozo
Jr.
et
al.
(2007)
and
Marques and Farah (2009) for mate leaves as well as by Pagliosa
t
al.
(2010b)
for
mate
bark.
Although
Pagliosa
et
al.
(2010b)
did not report the presence of epigallocatechin gallate in mate
bark, in this present study it was the polyphenol that showed
he
highest
concentration.
Bracesco
et
al.
(2010)
show
that
mong 26% of the major organic components of I. paraguarien-
is extracts are the catechins. Moreover, Streit et al. (2007) also
