Compounds or substances which act to reduce nutrient intake, digestion, absorption and utilization and may produce other adverse effects are referred to as antinutrients or antinutritional factors. Plant sources contain in their raw state wide varieties of antinutrients which are potentially toxic. The some major antinutrients includes: saponins, phytic acid, protease inhibitors. The proximate and phytochemical composition of Chlorophytum comosum was determined. Our results show that Chlorophytum comosum root tubers is rich in carbohydrates (65.84% DW) and fibre (17.24% DW), with high contents of ash (10.38% DW), and crude protein (4.56% DW). The phytochemical screening revealed moderate phytate and alkaloids contents. Amounts of polyphenols, saponins and steroids were low, absence and very high respectively. Therefore, Chlorophytum comosum is a rich source of proteins, fibers and carbohydrates, and are potential source of nutraceuticals. These antinutrients pose a major constraint in the use of plant protein sources in livestock feeds without adequate and effective processing. The level or concentration of these anitnutrients in plant protein sources vary with the species of plant, cultivar and post-harvest processing treatments.
