Abstract

A survey of the free amino acids and organic acids in the shoot of Phyllostachys edulis was made by means of amino acid autoanalyzer and gas chromatograph. The results of the survey are summerized as follows. 1. Eighteen amino acids found in bamboo shoot were lysine, histidine, arginine, tryptophan, aspartic acid, glutamic acid, threonine, serine, proline, glycine, alanine, valine, leucine, isoleucine, methionine, tyrosine and phenylalanine, and an unknown was found. Serine showed the highest amount and more than about 44% of total free amino acids. 2. Oxalic acid was the major organic acid, and formic acid, acetic acid, maleic acid, succinic acid, fumaric acid, citric acid, tartaric acid and sorbic acid were determined, and two unknown were found.

P. edulis순(荀)의 free amino acid 및 organic acid의 종류(種類)와 함량(含量)을 측정(測定)한 결과(結果)는 다음과 같다. (1) Free amino acid는 18종(種)이 검출(檢出)되었는데, lysine histidine arginine tryptophan aspartic acid glutamic acid threonine serine proline glycine alanine valine methionine isoleucine leucine tyrosine phenylalanine 등 17종(種)이 정량(定量)되었으며 이들 중 serine이 가장 많았고, 1종(種)은 미확인(未確認)되었다. (2) Organic acid는 11종(種)이 검출(檢出)되었으며 이들 중 formic acid acetic acid oxalic acid maleic acid succinic acid fumaric acid citric acid tartaric acid sorbic acid 등 9종(種)이 확인(確認)되었고, 이들 중 oxalic acid가 가장 많아 291.14mg%이었으며, 2종(種)은 미확인(未確認)되었다.
