摘要：

A spectrophotometric procedure is proposed for the determination of total free amino acids after reaction with o-phthalaldehyde and N-acetyl-l-cysteine, using isoleucine as the reference. The procedure was applied to the analysis of five samples of widely different composition. Recoveries were 98-105%. © 1990.
