The fraction had the same mobilities as standard theanine in amino acid analyzer and in paper chromatography. Hydrolysis of the fraction with chloric acid or glutaminase produced an equal molar ratio of glutamic acid and ethylamine. The hydrolysis of the fraction with glutaminase showed that the ethylamine was located at γ-position. The glutamic acid was shown L-form by glutamic acid hydrogenase (GluDH). IR spectrum of the fraction was identical to that of the standard as shown in FIG. 1. The isolated substance was confirmed theanine by these results.
