Hepatic and hematologic effects of fractions of Globimetula Braunii in normal albino rats

Globimetula braunii, a major medicinal plant used in traditional medicine in Nigeria, was evaluated for possible effects on hepatic and hematologic indices in Wister albino rats. The crude methanol extract of the plant was successively fractionated with hexane, chloroform, ethyl acetate, butanol and water. The MeOH extract of G. braunii and its fractions were administered to albino rats at a dose of 200 mg kg-1 body weight for 14 days. Assessments of liver function enzymes aspartate amino transferase (AST), alanine amino transaminase (ALT), as well as total and direct bilirubin levels were carried out. We observed significant increases (p≤0.05) in packed cell volume (PCV) and hemoglobin (Hb) in the rats treated with chloroform extract (CHCl3), ethyl acetate (EtOAc) and water (H2O) fractions. The red blood cell (RBC) count increased (p<0.05) after administration of CHCl3 and EtOAc fractions while white blood cell (WBC) count increased (p<0.05) in the crude and all its fractions except butanol. Significant decreases (p0.05) in enzyme activities in the MeOH fraction. However, the administration of other fractions to the rats, led to increases (p<0.05) in the activities of both enzymes. Total and direct bilirubin showed increases (p<0.05) in EtOAc and hexane fractions while only direct bilirubin increased (p<0.05) in the crude fraction. The present study demonstrates that G. braunii chloroform fraction has an influence on hematologic functions and liver enzyme levels in rats

Identification of protein types in Bambara nut seeds: perspectives for dietary protein supply in developing countries

This study aims to identify the types of proteins in malted and dry Bambara groundnut seeds and through a comparative analysis, identify similarities and their known uses. Dry viable bambara seed was stored for five days to malt. The proteins in the dry and malted seed were subsequently extracted in potassium phosphate buffer pH 7.0 and precipitated with saturated ammonium sulphate. MudPit (multidimensional protein identification technology) and LC-MALDI TOF-TOF (liquid chromatography - matrix-assisted laser desorption ionization tandem time-of-flight) mass spectrometry were thereafter used to identify the different types of proteins. A total of ten and twelve different types of proteins present in other legume species were identified in the malted and dry seeds respectively from the 214 peptides isolated after searching 586 proteins of the genus Vigna. Seed storage protein B and vicilin were observed to be the major proteins common to both malted and dry seeds and are similar to Vigna luteola. Some of the other proteins observed showed amino acid sequence homology with Vigna radiata and Vigna unguiculata species. The following proteins BV1, Heat shock and Bowman-Birk Inhibitor (a protease), were observed only in the malted state. This information may enhance the appreciation of the nutritional and health benefits of the seed
