Fresh leaves of Ailanthus excelsa and three protein fractions, unfract
ionated, chloroplastic, and cytoplasmic, as well as pressed cake left
after extraction of protein were subjected to proximate analysis. The
cytoplasmic protein fraction contained 62.71% crude protein, while who
le leaf contained 20.86%. The unfractionated and chloroplastic protein
fractions contained more crude fat than the whole leaf and pressed ca
ke. Compared to whole leaf and pressed cake, protein fractions were lo
w in crude fiber. The presence of polyphenols was also studied. The am
ino acid composition of the cytoplasmic fraction also showed an excell
ent balance of essential amino acids. Results indicated that the leaf
protein fractions from A. excelsa were nutritionally superior to the w
hole leaf, pressed cake, and soyabean protein.
