Résumé:
In the field of the biochemistry of natural plant substances and in particular the valorisation of oil plants, the aim of
this work is to extract and prepare savons from the base of Prunus Amygdalus (Algeria) and Carthamustinctorius
(Morocco and Algeria) oils, and to detect microbial activity in these soaps.
Extraction of almond seeds and safflower (Algerian and Moroccan) by the soxhlet method (extracted with hexane)
gave respective yields of the order (40.96%, 15.38%, and 18.7%). Physical test values revealed the purity of our
oils.the values obtained for the various chemical indices (acid, saponification, ester, alteration and peroxide) are
respectively:(2.98 mgKOH H /g,, 145.86 mgKOH H /g,, 145.86, 2.04, 6.38 meqO2/Kg) for almond oil, (4.08
mgKOH H /g,,185.13 mgKOH H /g,, 181.12, 2.16, 8,55 meqO2/Kg) for Algerian safflower oil, (3.92,
176.171,172.90, 2.15, 10.89 meqO2/Kg) for Moroccan safflower oil.
The antibacterial activities of almond and safflower soaps (Algerian and Moroccan) on pathogenic bacterial strains
(Bacillus cereus and Pseudomonas aeroginosa) shows that the antimicrobial power of these prepared soaps is
different (very strong, strong and medium) for Moroccan safflower, almond and Algerian safflower, respectively
