Antityphoid and radical scavenging properties of the methanol extracts and compounds from the aerial part of Paullinia pinnata.
[typhoid]
Paullinia
pinnata
Linn
(
Sapindaceae
)
is
a
medicinal
plant
,
locally
used
in
the
West
Region
of
Cameroon
for
the
treatment
of
typhoid
fever
.
This
work
was
designed
to
evaluate
the
antityphoid
and
antioxidant
activities
of
the
extracts
and
compounds
of
P
.
pinnata
.
The
methanol
extracts
of
the
leaves
and
stems
were
tested
for
antityphoid
and
antioxidant
activities
.
Compounds
were
isolated
,
and
their
structures
elucidated
by
analysis
of
spectroscopic
data
in
conjuction
with
literature
data
and
tested
for
the
same
activities
.
The
leaf
extract
was
also
tested
in
vivo
for
its
antityphoid
potential
in
a
Salmonella
typhimurium-induced
typhoid
fever
model
in
Wistar
rats
.

.
The
maximum

(

had
comparable

and
oxytetracycline

.
The
extract
induced
significant
dose-dependent
increase
of
WBCs
and

.
These
results
support
the
ethnomedicinal
use
of
P

pinnata
and
its
isolated

could
be
useful
in
the
standardization
of
