In this present study, in vivo antiplasmodial and antioxidant activities of Acacia gourmaensis A. RICH. (Mimosaceae) were evaluated based on its total extracts (ethanol-water, decoction, acetone), fractions (hexane fraction, ethyl acetate fraction, butanol fraction and aqueous fraction) and mineral contents. Total extract of decoction, acetone and EtOH-H2O fractions were used to evaluate chemical composition using HPLC-GC/MS-DAD methods. This plant is used in traditional medicine against liver disease, fractures, coughing fits and especially paludism. The antioxidant property was analyzed using 3 methods such as total antioxidant activity (TAC), iron reducing power (IRP) and radical scavenging activity (DPPH*). Antiplasmodial activity was performed in mice using red blood infected by Plasmodium berghei. The biological activities (antioxidants and antiplasmodial) were directed against plant phytochemical content 9 polyphenolic compounds were highlighted in the HPLC-DAD method, against 3 in HPLC- GC/MS. EtOH-H2O gave the best anti-TAC with 6.53 ± 0.15 mgEAA/mL. However, this extract (EtOH-H2O) gave the weakest activity with radical scavenging activity (23.73 ± 0.11 µg/mL). The best anti-DPPH* is obtained with acetone extract (1.93 ± 0.05 µg/mL). Concerning anti-IRP activity, hexane fraction gave the best result with 0.12 ± 0.00 µg/mL. At the antiplasmodial level, the best percentage reduction (19.9 %) is obtained with a dose of 150 mg/kg. On the phytochemistry plan, aqueous and ethyl acetate fractions given the best content with respectively 119.14 ± 8.13 mg EAG/g for total phenolic and 5.33 ± 0.17 EQ/g for total flavonoids. Mineral content quantification show that this plant is rich in calcium with 23.43 ± 1.32 mmol/L. The results due to the antiplasmodial activity could justify the traditional use of this plant.
