title: Bioactive and nutritive compounds in Sorghum bicolor (Guinea corn) red leaves and their health implication.
abstract: Sorghum bicolor L. Moench (Naga Red) red leaves is an ingredient used in rice and beans that is known as "waakye" in the Hausa language in some African countries. Little is known about its benefits aside from its colourant properties. We studied its bioactive, nutritive compounds and the effectiveness of four organic solvents (methanol, ethanol, acetone and diethyl ether) in isolation of these compounds to gain information regarding its health benefits to consumers. Of the compounds evaluated, the leaves consisted primarily of carotenoids, flavonoids and phenolic acids with small amounts of chlorophyll (a and b), lycopene and β-carotene. The fatty acid profiles of the leaves revealed palmitic, stearic, oleic and linoleic acid as predominant with each having greater than 5% of the total fatty acid identified. The nutritional implication of these findings is that the consumption of diets prepared with the leaves provides natural antioxidant and essential fatty acids that could fight cardiovascular related diseases.
