The antibacterial activity of the aqueous, ethanol, methanol and petroleum ether Soxhlet extracts of sundried stem bark of Spathodea campanulata P. Beauv. (Bignoniaceae) was investigated by testing the extracts against B. subtilis, E. coli, P. aeruginosa and S. aureus. The minimum inhibitory concentration (MIC) of the methanol extract was determined against the four bacteria strains and C. albi...
Abtract: The ethanolic and aqueous extracts of the fruits of Tetrapleura tetraptera (Fabiaceae) and seeds of Delonix regia (Bojer ex Hook.) Raf (Fabiaceae) and Raphia vinifera L. (Arecaceae) were tested on the second instar larvae of Anopheles gambiae (L) at varying concentrations. With percentage mortality, T. tetraptera (59.17%) in ethanol was the most effective followed by D. regia (42.78%) ...
Effects of an aqueous extract of orthosiphon thymiflorus on acetyl choline induces contraction on isolated frog rectus abdominis muscle were studies. The aqueous extract of orthosiphon thymiflorus produced significant inhibitory effect on the dose response curve of acetyl choline. It is concluded that the aqueous extract of orthosiphon thymiflorus may exert an inhibitory effect on the skeletal...
objectives the current study aimed to investigate the immunostimulatory effects of the aqueous extract of heracleum persicum on mouse peritoneal macrophages. background the immune system provides protection against infectious diseases that are caused by various microorganisms, in particular pathogenic fungi. utilization of herbal immunostimulants is one solution to improve the immunity of human...
Background and Objectives: The extensive use of chemical drugs for the treatment and control of chronic and infectious diseases as well as colorectal cancer, has led to an increased demand for natural and safe drugs and preservatives. Therefore, this study aimed to evaluate the presence of functional groups of constituents, total phenol and flavonoids content, radical scavenging potential, and ...
PURPOSE This study is aimed at determining chemical constituents and antimicrobial activities of a common brand of black tea (Lipton®) in Nigeria. METHOD Standard methods were employed for testing carbohydrates, tannins, saponins, flavonoids, alkaloids, steroids and terpenes in the tea. Antimicrobial activities of methanolic and aqueous extracts of the tea on four standard strains of organism...
The antimicrobial activity of aqueous extract leaf and stem of Santalum album was performed against Escherichia coli, Staphylococcus aureus and Pseudomonas. S. album leaf extract showed inhibition to E.coli (0.8mm), Staphylococcus aureus (1.0mm) and Pseudomonas (1.4mm) were as stem extract showed inhibition on E.coli (0.6mm), Staphylococcus aureus (0.4mm) and seudomonas (1.0mm) respectively. Ho...
artemisia species, growing in almost all the northern hemisphere, is used in folk medicine of some countries as a remedy for hypertension. since some cardiovascular disorders including hypertension are accompanied with altered responsiveness of vascular alpha-adrenergic receptors, the effect of aqueous artemisia annua extract (100 and 200 mg kg-1) on a1-adrenoceptor agonist-induced contraction ...
Introduction: The present study aimed to investigate the protective effects of Pimpinella anisum L. ethanolic and aqueous extracts on L-asparaginase- associated hepatotoxicity in rats using histopathological and specific 99mTc-Phytate biodistribution studies. Materials and Methods: 60 female rats were divided into 9 treatment groups including L-asparaginase group, Aqueous extract (100 and 200 m...
Ocimum gratissimum is a common plant in the tropics and has been used in food and medicine. Its usage in food and medicine could be attributed to its phtyochemical and antimicrobial properties. In this study we investigated the proximate, phytochemical, and antimicrobial attributes of air dried leaves of O. gratissimum. The aqueous extract was found to contain phtyochemicals with alkaloid and s...
