The leaf extracts of two medicinal plants Asystasia gangetica (L) and Newboulia leavis (p. Beauv) were assessed for anti-snake venom activity in vivo using mice. The result of the phytochemical analysis revealed that the two plants contain flavonoids, glycosides, saponins, tannins and alkaloids. The methanolic extracts of the two plants A. gangetica (L) and N. leavis (p. Beauv) significantly (p< 0.05) neutralized the Naja melanoleuca venom-induced lethality activity in the mice. The extracts (flavonoids, tannins and saponins) of the two plants also showed significant (p<0.05) neutralization of the venom–induced lethality activity in mice. The work confirmed that Asystasia gangetica and Newbouldia leavis possess significant anti-venom activity and can therefore be used in the treatment of snake bites.

This study was aimed at determining the optimum yield of bioethanol (as biofuel and industrial chemical) from yam, potato, watermelon and pineapple peels using different concentrations of hydrochloric acid (HCl). Results obtained from acid hydrolysis, fermentation and distillation revealed that yam peel gave the highest quantity of glucose (38.7±0.90%) and ethanol (18.40±0.18%) at an acid concentration of 1.5M, watermelon peel equally recorded a highest yield of glucose (18.3±0.50%) and ethanol (8.35±0.14%) at 1.5M. For potato peel, the highest quantity of glucose (33.8±1.10%), and ethanol (18.23±0.04%) was at 2.0M, this concentration (2.0M) was equally the optimum for pineapple peel, the highest glucose concentration and ethanol yield of which was 24.5±0.62% and 11.44±0.29% respectively. Utilizing these agro-wastes for the production of bioethanol provides a means of recycling these biological wastes which are normally prone to rapid microbial spoilage.
