Different parts of Cynara cardunculus, var. scolymus L., have been used in traditional medicine to treat various disorders and as a coagulant in cheese making. In this work, phenolics from different parts of globe artichoke of the local cultivar “Violet d’Alger” (outer and inner bracts, stem, choke, and heart) were extracted by the Soxhlet method and partially purified. The extraction yield and purification yield were determined, and phenolic compounds were analyzed by the Folin-Ciocalteu method. Thin-layer chromatography was performed and the antioxidant activity by 2,2-diphenyl 1-picrylhydrazyl (DPPH.) scavenging assay was achieved. Antibacterial and antifungal activities were estimated against the following bacteria and fungi: Bacillus subtilis, Geobacillus stearothermophilus, Staphylococcus aureus, Escherichia coli, Aspergillus fumigatus, and Candida albicans. Results showed that all extracts had considerable amounts of phenolics with a concentration-dependent antioxidant activity and an effectiveness against bacterial and fungal strains. Among the different parts of globe artichoke, the choke exhibited the highest phenolic content, antioxidant activity, and antimicrobial effect. Full article
