摘要

The nutritional, phytochemical, antioxidant and antibacterial activities of the acetone, methanol and waterextracts of the leaves of Amaranthus asper were investigated using standard analytical methods in order to assess thenumerous potential of the plant leaves. The proximate analysis showed that the leaves of this plant contained moisture,ash, crude protein, crude lipid, crude fibre, energy and carbohydrate. Elemental analysis in mg/100 g (DW) indicated thatthe leaves contained sodium (0.0373), potassium (2.872), calcium (2.504), Magnesium (0.569), Iron (419), Zinc (26),phosphorus (0.177), Copper (18), Manganese (91), and Nitrogen (1.78). The chemical composition in mg/100 g (DW) foralkaloid, saponins, and phytate were 0.3, 7.0 and 9.25 respectively. Comparing the nutrient and chemical constituents withrecommended dietary allowance (RDA) values, the results reveal that the leaves contain an appreciable amount ofnutrients, minerals, and phytochemicals and low levels of toxicants. At 1mg/ml, the acetone extract caused 98.2% ABTSradical scavenging inhibition while the methanol, water and BHT caused inhibition at 95.4, 97.1 and 99.3% respectively.The result for DPPH scavenging activity was close to that of ABTS. The plant was also rich in the different polyphenolsanalyzed in this study. The ferrous reducing antioxidant power (FRAP) values for acetone extract (1084.9) is much higherthan that of methanol (143.5), water (42.4), BHT (63.5), and catechin (972.02) but lower than those of ascorbic acid(1632.1) and quercetin (3107.3). The methanol extract has antibacterial activity against all the Gram-positive organismsused in this study. This study has to some extent validated the need for the use of the leaves of Amaranthus asper fornutritional and medicinal purposes.
