Abstract

Fresh green Vernoniaamygdalinaleaves,moringaoleifera leave and golden shower tree (cassia fistula)(asuwon) were analyzed for protein content, moisture, ash, minerals and antimicrobial activity. Leaves had a moisture content of 83.0% (dry matter, 17.02%), a protein content of 1.30% and ash content of 0.50%. Mineral content was as follows: phosphorus, 61.55 μg g-1; selenium, 8.2x10-3μg g-1. iron, 4.71μg g-1 and zinc, 1.13μg g-1, based on fresh weight of leaves. The aqueous extract of the leaves inhibited the growth of the gram +ve bacterium Staphylococcus aureusand the gram –ve bacterium Escherichia coli. The nutritional and food processing implications of the results are discussed.
