Abstract: The present study aims to evaluate the proximate composition of proteins (Crude as well as soluble protein) and some amino acids in shade-dried leaf samples. The photosynthetic active green foliage of grasses, legumes and other plants contains in general high amounts of proteins and amino acids. Protein is a food component that has functional properties that affect the properties of food products. In the present investigationshade driedleaves samples from seven different plant species viz. Berseem (Trifolium alexandrium L.), Alysicarpus vaginalis L. var. stocksii., Alternanthera paronychioides St. Hil., Cabbage (Brassica oleracea L. var. capitata), Radish (Raphanus sativus L.), Adulsa (Adhatoda vasica Nees.), and Bauchi (Psoralia corylifolia L.) were prepared and was assessed for proteins and amino acids. The prepared sample has 6-26% crude protein and 1-14% soluble protein. The amino acids like methionine and tryptophan range from 0.171-2.262 g / 16gN.
