Studies on the Constitutents of the Leaves of Perilla frutescens $B_{RITTON}$ -Identification of Free Amino Acids-

들깨잎의 성분연구 -유리 Amino산의 분석-

By means of the two-dimensional thin-layer chromatography, free amino acid components of the leaves of $Perilla\;frutescens\;B_{RITTON}$ have been examined and twelve spots have been detected by the coloration with ninbydrin reagent. These were found to be aspartic acid, asparagine, alanine, phenylalanine, tryptophan, leucine, glutamic acid, proline, threonine, histidine, cystine, and glycine, tentatively.
