ABSTRACT: This study investigates the phytochemical composition and antioxidant activity of extracts from the trunk bark of Lannea microcarpa, a tree traditionally used in Mali for various medicinal purposes. The sample was collected in Kayes. The polyphenols, flavonoids, tannins and anthocyanins of the extracts were quantified using spectrophotometry and identified via HPLC. The antioxidant activity was assessed using 2, 2-azinobis-3-ethylbenzothiaz oline-6-sulfonic acid (ABTS) and 2, 2-Diphenyl-1-Picrylhydrazyl (DPPH) radicals scavenging capacities. The extracts were mainly rich in flavonoids; Polyphenols, tannins and anthocyanins were very low. The values were 44.50 mg ECt; 1.89 mg EAG; 1.01 mg ECt; 0.57 mg ECG per 1 g of dry matter (DM) respectively for flavonoids, polyphenols, tannins and anthocyanins. The HPLC analysis of the sample revealed the presence of a Caffeic acid 37.51 µg per 100 mL. Our extracts showed good ABTS and DPPH radical scavenging capacities. The antioxidant activities of sample correlated with their contents in total phenolic and total flavonoids.
