Background: Combretum hypopilinum is used in Togolese traditional medicine to alleviate various ailments including hepatic disorders. Objective: This study evaluates the hepatoprotective activities of crude ethanolic extract of C. hypopilinum root bark (CECH) and its possible mechanism(s) of action in Wistar rats. Materials and methods: In vitro antioxidant potential was evaluated using DPPH, Ferric-reducing power and hydroxyl radical scavenging assays. Hepatoprotective activity was assessed using CCl4-induced acute hepatotoxicity in rats. Animals were pretreated orally with different doses of CECH (200 and 400 mg/kg) once daily for 7 consecutive days and were subjected to intraperitoneal single injection of CCl4 (1 mL/kg). Serum markers of hepatic damage, hepatic endogenous antioxidants, NO, TNF-α and lipid peroxidation contents were measured out. Results: The pretreatment with CECH significantly decreased levels of hepatic enzymes (p \< 0.05, p \< 0.01, p \< 0.001) and MDA in pretreated rats (p \< 0.05, p \< 0.01). CECH restored the decreased levels of hepatic antioxidants including SOD (p \< 0.01), CAT (p \< 0.05 at 400 mg/kg) and GSH (p \< 0.05 at 400 mg/kg) and significantly inhibited hepatic production of NO (p \< 0.05, p \< 0.01). as well as the level of TNF-α (p \< 0.001) in pretreated rats. Protective effects of CECH were confirmed by histopathological examinations. CECH exhibited antioxidant in vitro and contains also total phenol and flavonoid. Conclusion: This study suggests that CECH protected the liver from CCl4-induced hepatic damage possibly via antioxidant and anti-inflammatory mechanisms.

Background: Jatropha multifida is used in Togolease folk medicine for the healing of chronic wounds. Objective: This study aims to investigate antibacterial, anti-inflammatory and antioxidant activities of the leaves ethanolic extract. Materials and Methods: The antimicrobial activity was assayed by National Committee for Clinical Laboratory Standards broth microdilution method on strains of Staphylococcus aureus and Pseudomoas aeruginosa isolated from wounds, whereas the anti-inflammatory activity was performed by carrageenan and histamine induced paw edema method in rat modele. The 2, 2-diphenyl- 1picrylhydrazyl (DPPH) free radical scavenging and ferric reducing antioxidant power (FRAP) were used for the antioxidant activity. Results: The antibacterial assay showed an in vitro growth inhibition of P. aeruginosa and S. aureus in dose-dependent manner, with minimum inhibitory concentration values ranging from 2.5 to 3.12 mg/mL for S. aureus and from 6.25 to 12.5 mg/mL for P. aeruginosa. The maximum paw anti-inflammatory effect occurred after 3 and 5 h administration of histamine and carrageenan, respectively. The DPPH radical scavenging and the FRAP assays yielded weak antioxidant activity. Conclusion: J. multifida possesses antibacterial and anti-inflammatory activities that could justify the use of the plant for the treatment of wounds in the folk medicine. Key words:

Background: In Togo, malaria constitutes a major public health problem but, until now, the population still mostly relies on herbal medicine for healing. This study aimed to document medicinal plants used for malaria therapy in the Plateau region of the country. Methodology: Semi-structured questionnaire interviews were used to gather ethnobotanical and sociodemographic data from traditional healers of the study area. Results: A total of 61 plants species belonging to 33 families were found to be in use for malaria therapy in the Plateau region. Caesalpiniaceae were the most represented family with 7 species, followed by Euphorbiaceae and Poaceae with 4 species each. According to the relative frequency of citation (RFC), Newbouldia laevis Seem. (RFC =0.52), Sarcocephalus latifolius (Sm.) E.A. Bruce (RFC =0.48), Acanthospermum hispidum DC. (RFC =0.43), and Senna siamea (Lam.) H.S. Irwin and Barneby (RFC =0.40) were the most cited in the treatment of malaria in the traditional medicine in the Plateau region. The parts of plants used could either be the barks, roots, leaves, or whole plants. The recipes also could be a combination of various species of plants or plant parts. Conclusion: This study highlights the potential sources for the development of new antimalarial drugs from indigenous medicinal plants found in the Plateau region of Togo. Such results could be a starting point for in vitro antimalarial screenings.
