In:
International journal of pharmacy and pharmaceutical scienceSummary: Objective:
This
work
aimed to
screen
the antioxidant activity of marine macroalgae from the Moroccan Atlantic coast (region of El Jadida).
Method
s:
Evaluation of the antioxidant activity of different collected species, lyophilized and extracted with a solvent mixture
chloroform
/methanol
(2/1; v
/v)
was
conducted according to two techniques, first by thin layer chromatography (
tlc
) then by spectrophotometry,
using a free radical 2,2
-diphenyl
-1-picrylhydrazyl (
dpph
). The sampling on a distance of 110 km allowed to harvest 86 algal specie
s (16 brown
algae, 47 red algae, 14 green algae and 9 algae
being identified).
Result
s:
The analys
is by thin layer chromatography reveals an antioxidant activity in nearly half of harvested algal species (52.32 %). This act
ivity
varies depending on the concentration of the extract and in function of incubation time in the presence of
dpph
. The monitori
ng of the
kinetic
s of
degradation of
dpph
by spectrophotometer in the presence of extracts which were active by
tlc
allowed to confirm the results and select the most
active algal species based on the percentage of remaining dpph
in the medium after 120
min of reactio

can be a promising source of natural
compounds endowed with high
antioxidant potential.
