Antiplasmodial and analgesic effects of crude ethanol extract of Piper guineense was investigated in mice. The antiplasmodial and analgesic efficacy of the extract was judged on its ability to reduce parasitemia and writhing, respectively, in mice. The antiplasmodial screening involved treating infected mice with 200, 400, and 600 mg/kg body weight of extract while the positive control group wa...

Considerations on antioxidants derived from plants have continuously increased during this decade because of their beneficial effects on human health. In the present study we investigated the free radical scavenging properties of extracts from Piper guineense (P. guineense) and their inhibitory potentials against oxidative mediated ion toxicity. The free radical quenching properties of the extr...

three different solvents namely; hexane, ethyl acetate and ethanol were used in partitioning the extracts obtained from piper guineense seeds and solvent extracts were investigated for the presence or absence of secondary metabolites. extracts were further evaluated on adult maize weevils, sitophilus zeamais. experiment was carried out under laboratory conditions at 27 ± 2 °c ambient temperatur...

The rehydration characteristics of dehydrated West African pepper leaves were investigated at hydration temperatures of 28, 60, 70, and 80°C. Four treatments were given to the leaves: blanched and sun dried, unblanched and sun dried, blanched and shade dried, and unblanched and shade dried. The hydration process of the dehydrated leaves was adequately described by the Peleg's equation. As the h...

The aim of this study was to evaluate the antimicrobial activity of aqueous extract of Psidium guineense Swartz (Araçá-do-campo) and five antimicrobials (ampicillin, amoxicillin/clavulanic acid, cefoxitin, ciprofloxacin, and meropenem) against twelve strains of Staphylococcus aureus with a resistant phenotype previously determined by the disk diffusion method. Four S. aureus strains showed resi...

Contact activities of Piper guineense (Schum and Thonn) Eugenia aromaticum (L). (Merril Perryl) extracts in the control Dermestes maculatus larvae infesting stored fish (Clarias gariepinus) were investigated under laboratory condition (28 ±3°C 65±5% RH). The tested by application 2.0 µL each to ten third instars using micro pipette at a concentration 6.00, 10.00 20.00% p...
