Abstract
The tree spinach ( Cnidoscolus spp., Euphorbiaceae), called chaya in south Texas, is popular in Mexico and Central America and has been introduced into the United States (mainly Texas and Florida) for potential uses as a leafy vegetable plant. Nutritional composition of raw and cooked leaves of two chaya species ( C. chayamansa and C. aconitifolius ) were determined and compared with nutritional composition of spinach ( Spinicia oleraceae ). While the two chaya species contained substantially greater amounts of mineral nutrients and vitamins than spinach, no significant differences were found in the amounts of mineral nutrients and vitamins, except in relative compositions of fatty acids and amino acids, among the chaya species. Cooking slightly reduced nutritional composition of both chaya and spinach leaves. Because of the presence of toxic hydrocyanic glycosides in chaya leaves, cooking, which inactivates the toxic compound, is essential.
