Ethanol

The study evaluates the gastro-protective activity of methanol extract of the leaves of Polyalthia longifolia (Sonn.) Thw. in Wistar rats. Single daily dose of the extract (200, 400 and 800 mg/kg body weight) were administered orally to the respective groups of experimental rats for 28-consecutive days. The control and standard groups received distilled water and ranitidine (10 ml/kg and 250 mg/kg body weight) respectively. At the end of the period, they were exposed to a single oral dose of 75% ethanol.

Ethanolic root extract of Anacardium occidentale L. was evaluated for antimicrobial activities against selected clinical isolates. Bacteria and fungi pathogens obtained from the laboratory unit of a functional health facility for this study included Escherichia coli, Kblesiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris, Streptococcus sp., Candida albicans and Aspergillus niger. The identities of the bacteria spp. were re-established following standard physical and biochemical routines.
