Lysine, histidine, arginine, tryptophan, aspartic acid, glutamic acid, threonine, serine, proline, glycine, alanine, valine, leucine, isoleucine, methionine, tyrosine and phenylalanine were presented in the leaves of A. altissima, and glutamic acid showed the highest amount and was more than about 48% of total free amino acids. 2. Fumaric acid was the major organic acid in the leaves of A. altissima, and also formic acid, acetic acid, maleic acid, succinic acid, oxalic acid, citric acid, tartaric acid and sorbic acid were determined, and two unknown were found.
