The occurrence of drug resistant bacteria warrant investigation on herbal plants for effective antibacterial agents. Vernonia glaberrima leaf (VGL) and stem (VGS) hexane extracts were subjected to analysis by gas chromatography-mass spectrometry (GC-MS) and subsequently evaluated for antibacterial activity alone and in combination each with Sparfloxacin (SPX) and Ciprofloxacin (CPX) on selected bacteria including resistant species. GC-MS analysis revealed fatty acid esters, triterpenoids and aro...

Lipids possess versatile biological properties in human health and nutrition. The compositions of lipids were investigated on the raw, boiled and fermented seeds of Pentaclethra macrophylla n-hexane extracts. The seed extracts were esterified, and chemical composition of the fatty acids was evaluated using gas chromatography-mass spectrometry (GC-MS). Subsequent chromatographic purification and isolation on the lipids was carried out using column chromatography and thin layer chromatographic tec...

In an attempt to search for new and efficient antifungal agents, five chalcones namely (E)-3-(4′-diethylaminophenyl), (E)-3-(2′-ethoxyphenyl), (E)-3-(3′,4′-diethoxyphenyl), (E)-3-(2′,3′-dihydrobenzofuran-5-yl) and (E)-3-(3′,5′-bis[trifluoromethyl]phenyl)-1-(2-hydroxyphenyl) prop-2-en-1-one were synthesized from 2-hydroxyacetophenone with the corresponding substituted benzaldehydes. The synthesized chalcones were characterized by GC–MS, FTIR, 1H NMR and 13C NMR spectra analysis. The antifungal ac...

Pavetta corymbosa is a medicinal plant used as remedy for infectious diseases in Nigerian traditional medicine. In this study, analysis of chemical composition of lipophilic extract and the antimicrobial activity of the extract were carried out with a view to discovering effective phytomedicine. The gas chromatography-mass spectrometric (GC-MS) analysis carried out showed that 9-methyl octadecanoic acid- ethyl ester (22.6%), cyclotetracosane (15.3%), 2,4,6-trimethyl hexacosanoic acid- methyl est...

Background: Vernonia species are widely consumed as vegetables or medicinal herbs for the treatment of various human diseases in Nigeria. Nevertheless, there exists a growing concern for consumption safety of those herbal plants, due to increasing environmental pollution. This is because plants can accumulate some heavy metals that constitute a potential risk to human health. Nonetheless, also essential elements may be accumulated in plants, which provide nutrients for combating diseases and mai...
