Résumé:
Plants have always played a very important role for mankind, as they can produce a large
number of complex organic molecules that are often involved in biological activities. The
objective of this study was to detect the phytochemical compounds and the antioxidant and
antibacterial properties of the hydro-ethanolic extract of Retama sphaerocarpa.
The yield of the hydro-ethanolic extract of the aerial part of Retama Sphaerocarpa was
23.18%. The results of the antioxidant activity show a significant antioxidant power of the
extract compared to vitamin C, also known as ascorbic acid, which is a preferred antioxidant
and the DPPH assay allows us to conclude that the percentage of DPPH free radical
inhibition is high in the hydro-ethanolic extract of Retama sphaerocarpa with an EC50 =29,
48μg/mL.
The results obtained using the microdilution method show interesting antibacterial
activity.
