The study was designed to evaluate the hepatoprotective activity of different solvent extracts (hexane, chloroform, ethyl acetate and methanol) of Enantia chlorantha stem bark in acute experimental liver injury induced by acetaminophen. The effects observed were compared with a known hepatoprotective agent, silymarin (100 mg/kg p.o.). Preliminary phytochemical tests and acute toxicity study wer...

BACKGROUND The plant, Chrysophyllum albidum is indigenous to Nigeria and its stem-bark has wide application in traditional medicine for the treatment of infections and oxidative stress related diseases. The aim of the study was to isolate the chemical constituents responsible for the antioxidant and antibacterial activity from the stem-bark of the plant in order to justify some of its ethnomedi...

Although quinine, the active ingredient of chinchona bark, has been used in the treatment of malaria for several centuries, there is little information regarding the interactions of this drug with the human malaria parasite Plasmodium falciparum. To better understand quinine's mode of action and the mechanism underpinning reduced responsiveness, we have investigated the factors that contribute ...

Three to six hours after the administration of extracts of neem bark or flower, the blood glucose levels of normal and streptozotocin-induced diabetic mice dropped significantly. However, neem flower possesses stronger hypoglycemic activity than the bark. Hypoglycemic action of these extracts may be due to their metabolic effect on tissue and or due to increase in insulin secretion.

the plant bridelia ferruginea benth (euphorbiaceae) has been known for its use in the management of oral thrush ethnomedicinally in various parts of africa, a practice which has been justified by results of certain scientific studies. the aim of this study was to develop an appropriate dosage formulation, a mouthwash and evaluate the antifungal potential of this dosage formulation against a maj...

Stereospermum kunthianum, Cham, Sandrine Petit (family: Bignoniaceae) is used in traditional medicine to treat bronchitis, pneumonia and coughs, gastritis, wounds, rheumatic arthritis, ulcers, dysentery, leprosy and venereal diseases in humans. The antiinflammatory activity of the aqueous extract of the stem bark was investigated with experimental animal models using the carrageenan-induced paw...

The aim of this study was to develop nanoemulsion containing soft extract of stem bark of Rapanea ferruginea to improve the topical delivery and anti-inflammatory activity. The extract of R. ferruginea stem bark was incorporated into the oily phase of the nanoemulsion by the method of phase inversion at low energy. The developed nanoemulsion had an average droplet size of 47.88±8.20 nm and a po...

The effect of repeated administration of aqueous extract of Enantia chloranta stem bark on selected enzyme activities of rat liver was investigated. The aqueous extract of the plant was administered to white albino rats daily at 24hr interval at a dosage level of 100mg/kg body weight after which the rats were sacrificed after receiving 1, 3 and 5 daily oral doses. Administration of the extract ...

Mammea africana Sabine (Guttiferae) stembark, a common plant, traditionally used to treat various diseases and ailments was evaluated for hepatoprotective potentials against paracetamol- induced liver injury in rats. The hepatoprotective effect of the stembark extract (30-90 mg/kg) was evaluated by the assay of liver function parameters: total and direct bilirubin, serum protein and albumin, to...

The antibacterial efficacy of crude aqueous and ethanol extracts leaf, stem bark and roots of Datura metel at 20mg/ml were assayed against eight clinical bacterial isolates (Streptococcus b hemolytic, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Bacillus cereus and Streptococcus dysenteriae) by well in agar method The leaf and stem bark of the plant wa...
