Abstract
18 kinds of total amino acid in the crops mentioned in the subtitle grown in Japan were determined, whereby the microbiological assay method using lactic acid bacteria was employed throughout the study. When the values comprehending those appeared in Part 1 and 2 were surveyed, it was revealed that buckwheat belonging exceptionally to the family of Polygonaceae gave an amino acid pattern significantly differing in the several kinds of acid level from other subjects of Gramines conducted in the study. The necessity of further study to observe the botanical relationship from the amino acid of seeds or their protein was emphasized.
