Evaluation of Antioxidant, Immunomodulatory Activities, and Safety of Ethanol Extract and Fractions of Gongronema latifolium Fruit. INTERNATIONAL SCHOLARLY RESEARCH NOTICES 2014; 2014:695272. [PMID: 27433504 PMCID: PMC4897319 DOI: 10.1155/2014/695272] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/11/2014] [Revised: 07/29/2014] [Accepted: 08/13/2014] [Indexed: 11/30/2022]
Abstract
Gongronema latifolium fruit has wide application in ethnomedicine, especially in maintaining healthy living and general body healing. We therefore investigated the antioxidant, immunomodulatory activities, and safety of its ethanol extract and fractions. The in vitro antioxidant activities of the extract and fractions were determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) test while in vivo activities were determined using carbon tetrachloride (CCL4) induced oxidative stress. Cell and humoral mediated immune responses were also evaluated together with toxicity studies. The extract, ethyl acetate, and methanol fractions showed inhibition of DPPH radical with IC50s 120, 90, and 60 μg/mL, respectively. Methanol fraction at 200 mg/kg produced significant (P < 0.05) inhibition of lipid peroxidation (MDA conc. 1.2 μmol/L) compared to control (2.8 μmol/L). Both ethyl acetate and methanol fractions at 200 mg/kg produced significant (P < 0.05) phagocytic index of 0.021 and 0.025, respectively, compared with control (0.01). Significant (P < 0.05) elevations of white blood cells, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase were noticed on the 91st day at higher doses. Generally, this study justified the traditional use of G. latifolium fruit for general body healing and maintenance of healthy living. Long term administration is safe on the haematological and biochemical systems especially at lower doses and its toxicity at higher doses is reversible.
