Pulicaria is a genus of flowering plant in the Asteraceae family. It contains over 100 species. In this study the crude extract was prepared from the fresh leaves of P. glutinosa and further fractionated into three solvent to solvent fractions. The zebrafish (Danio rerio) embryos were treated with these extracts to explore the developmental toxicity. The crude extract did not show any significa...

The in vitro antibacterial activity of crude methanolic extract of the seeds of Garcinia kola was investigated. The extracts exhibited antibacterial activities with zones of inhibition ranging from 10 mm to 25 mm. The minimum inhibitory concentration of the diethyl ether fraction was between 0.313 and 5.0 mg/ml, while that of butanol fraction varied from 0.157 to 5.0 mg/ml. The butanol fraction...
