The aim of this study was to compare the effectiveness of the extracts obtained using the aeruginosa and S. typhiwith the lowest inhibitory zones. The MIC of the methanol extract against the organisms was 12.5, 12.5, 25 and 50 mg/ml respectively. The aqueous extract showed the least significant activity against S. aureus, E. coli, P. aeruginosa and S. typhi with MICs of 25, 25, 25 and 50mg/ml respectively.

Mushrooms are fungal fruit-bodies which have over successive years served as suitable source of protein, carbohydrates, minerals and vitamins. The fruit-bodies derive their nutrients from varieties of substrates including agro-wastes. This study was conducted to evaluate the potentials of using the pods of Delonix regia, straws of Saccharum officinarum and bark of Gmelina arborea in the production of nutritionally-rich edible oyster mushrooms, Pleurotus ostreatus and Pleurotus pulmonarius. The experiment was carried out in three replicates in the Department of Plant Science and Biotechnology, Michael Okpara University of Agriculture, Umudike. The results of the investigations were analysed using Analysis of variance (ANOVA), and the means were separated using Least Significant Different (LSD) tool. The result of the myco-chemical analysis shows that fruit-bodies of P. ostreatus var florida, produced in Saccharum officinale straw, yielded the higher alkaloids (3.93±0.010g/100g) than those produced in Gmelina+Delonix (3.84±0.025g/100g) and S. officinale+D. regia , (3.77±0.03g/100g). The trend was the same with Flavonoids, tannins, saponins and phenols from S. officinale, G. aborea + D. regia and S. officinale + D. regia, and D. regia. Pleurotus pulmonarius from the substrates contained low concentration of alkaloids but higher concentration of flavonoids, tannins, saponins and phenols. Generally the substrates yielded fruit-bodies that are rich in protein. However those from S. officinale + D. regia appeared richer in protein (28.44±0.03g/100g). The substrates showed encouraging potentials for use in the production of nutritionally-rich edible P. ostreatus and P. pulmonarius, with S. officinale + D. regia standing out as a more likely preferred substrates. There appears to be a synergism between the substrates of S. officinale and D. regia, since the mean of their individual performance is less than their performance when combined.

The anti-inflammatory and hepatoprotective properties of methanol extract of Arachis hypogea leaves were studied. At 400 mg/kg, the extract significantly suppressed the development of hind paw oedema induced by egg albumin, which compares favorably with a standard antiinflammatory drug aspirin (acetylsalicylate) which at 100 mg/kg inhibits egg-albumin induced rat paw oedema. It was observed that the extract significantly inhibited platelet aggregation in a dose Original Research Article
