Abstract
Background: The objective of this study was to evaluate the in vitro antibacterial activity of nanoemulsions based on the essential oils of Canarium schweinfurthii and Dacryodes edulis against enteric bacteria responsible for diarrhea.
Methods: The essential oils were extracted by the hydrodistillation method using a Clevenger-type apparatus, and the chemical composition was determined by gas chromatography with flame ionization detection (GC-FID) and gas chromatography (GC) coup...

Investigating the ethanolic extract of Desmodium uncinatum as a natural protector in streptozotocin-induced diabetic nephropathy in Wistar rats
Abstract
Background: Diabetic nephropathy is a severe microvascular complication of type 1 diabetes, often leading to chronic kidney disease. This study aimed to evaluate the renoprotective effects of the ethanolic extract of Desmodium uncinatum (EEDU) on renal dysfunction in streptozotocin-induced diabetic rats.
Methods: Type 1 diabetes was induced in male rats via intraperitoneal injection of a single dose of streptozotocin (STZ) at 60 mg/kg. After 72 hours, only animals with blood gluc...

Evaluation of anti-staphylococcal activity and acute toxicity of hexane extracts of Macaranga occidentalis (Mull. Arg.) Mull. Arg (Euphobiaceae)
Abstract
Background: Macaranga occidentalis is well known in traditional medicine for the treatment of various ailments like bruises, boils, cuts, sores, and diarrhea. This study aimed to investigate in vitro and in vivo the anti-staphylococcal activity of Macaranga occidentalis extracts on selected Staphylococcus aureus, including multidrug resistance (MDR) isolates. Moreover, the acute toxicity of the active extract was assessed.
Methods: Extracts were prepared by maceration of M. occid...

Assessment of in vivo acute, subacute toxicity, in vitro anti-plasmodial activity, and UPLC-ESI-QToF-MS/MS prediction of Annickia affinis (Exell) Versteegh & Sosef (Annonaceae) roots extract
Abstract
Background: Annickia affinis is a medicinal plant widely used in African traditional medicine to treat various diseases, including malaria. This study aimed to evaluate the toxicological profile, chemical composition, and antiplasmodial activity of the ethanolic (EtOH) root extract of Annickia affinis.
Methods: Acute (14-day) and subacute (28-day) toxicity studies were conducted in accordance with guidelines 423 and 407 of the Organisation for Economic Co-operation and Developmen...

Synergistic antibacterial activity of Erigeron floribundus extracts combined with erythromycin against multidrug-resistant bacteria
Abstract
Background: This research assessed the in vitro antibacterial activity of Erigeron floribundus extracts against multidrug-resistant bacterial strains and explored their potential to enhance the effectiveness of standard antibiotics through synergistic combinations.
Methods: Leaf, stem, and root crude extracts of E. floribundus were obtained using methanol and ethyl acetate. Major phytochemical groups (total phenols, flavonoids, tannins, saponins) were quantified. The antimicrobia...

Antidiabetic and antioxidant potential of powder blend of Vigna subterranea, Curcuma longa, and Piper nigrum in streptozotocin-induced rats
Abstract
Background: Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia and frequently associated with oxidative stress and metabolic complications. The present study evaluated the antidiabetic and antioxidant potential of a powder blend composed of Vigna subterranea, Curcuma longa, and Piper nigrum in streptozotocin-induced diabetic rats.
Methods: A mixture design approach was used to optimize the formulation of the powder blend based on total phe...

Investigation of heavy and trace metals contamination in palm wine and locally brewed alcohol from the Ashanti Region of Ghana
Abstract
Background: Palm wine and locally produced alcoholic beverages are widely consumed in rural communities in Africa, due to their perceived health benefits. However, their safety regarding heavy and trace metal contamination is lacking, particularly in Ghana. This study quantitatively assessed heavy-metal contamination in fresh palm wine (FPW), fermented palm wine (FEPW), freshly brewed alcohol (FAL), and stored alcohol (SAL) from 5 brewing sites in the Ashanti region of Ghana.
Met...
