Abstract:

Anthocleista liebrechtsiana is a plant species widely used in traditional medicine to treat bacterial infections. To provide a scientific basis to traditional uses of this plant species, it different extracts were evaluated for their antibacterial and antioxidant potential. Antibacterial activity was assessed using minimum inhibitory concentration. The presence of phytoconstituents was detected qualitatively. A. liebrechtsiana extracts displayed interesting antibacterial and antioxidant activities. The Gram positive bacteria S. aureus ATCC 33591 were more sensitive to Anthocleista liebrechtsiana than the Gram negative E. coli ATCC 27195. All the extracts tested were found to be biologically active against Staphyloccocus aureus except alcoholic extract of the leaves for which the bioactivity was moderate. The antibacterial activity was marked for the stem bark extracts (MIC ≤ 31.5 µg/mL) than those of the leaves (MIC ≤ 62.5 µg/mL). Methanol extract of A. liebrechtsiana displayed also interesting free radical Scavenging activity (IC50 < 10 µg/mL). Phytochemical analysis revealed the presence of total polyphenols, catechic tannins, alkaloids, saponins, terpenes and steroids. Antibacterial and free radical scavenging efficacy shown by this plant provides a scientific basis and thus, validates it traditional use as phytomedicine. Isolation and purification of different phytochemicals may further yield significant antibacterial and antioxidant agents.
