For porte un seuil d e detection, nous perrneteach sample, three extracts, prepared tant de mettre en evidence les especes les with E t 2 0 , then E t O H 99 %, then H,O, plus interessantes. were tested. The largest proportion of active species occurs in Cystoseiraceae, Bonnemaisoniaceae and Rhodomelaceae. Partie experimentale lntroduction La mer semble possider un certain pouvoir d ' a~t o e~u r a t i o n bactiriologique. Celui-ci serait dG, en particulier, aux algues [20]. Depuis une vingtaine d'annees, de nombreuses itudes ont ete faites sur ce sujet [2, 7, 14, 16, . .

A review of some antimicrobial compounds isolated from medicinal plants reported in the literature 1978–1988

“…(B) Some workers have looked for new sources of antimicrobial compounds in vegetable material from the sea, for example from marine algae (Caccamese and Auolina, 1979;Debro and Ward, 1979;Biard et al, 1980;Higgs, 1981;De Silva et ul., 1982;Gonzdlez et al, 1982Gonzdlez et al, , 1983Findlay and Patil, 1984;Nicod et al, 1985;Rodnguez-Iglesias and Mira-GutiCrrez, 1987;Benlismane et al, 1988;Hiroshi Kakisawa et al, 1988). The variety and novelty of compounds obtained has excited interest because of the possibility that they may exhibit novel mechanisms of action.…”

Aussi, parallelement i une etude sur les proprietes antibiotiques d'algues fixees de la c6te atlantique francaise [2], nous avons egalement recherchi, in vitro, d'iventuelles proprietes inhibitrices de la croissance cellulaire ou cytotoxiques.…”

First Report of Halopithys incurva (Rhodomelaceae, Rhodophyta) from the Marchica Lagoon of Nador (North-Est Morocco, Mediterranean)

“…Halopithys incurva plays an important role in several fields, such as chemistry. It is richer in chemical compounds, namely, arsenic, manganese and brominated compounds [13,14], is rich in halogenated E3S Web of Conferences 527, 01002 (2024) https://doi.org/10.1051/e3sconf/202452701002 JOE4 secondary metabolites [14,15] and, in particular, is rich in polyphenols with high antioxidant power [15]. Halopithys incurva acted as a good inhibitor of carbon steel corrosion in acid [16].…”
