This study was carried out to investigate amino acid contents of golden mushroom and pink mushroom. The amino acid analysis was followed by AccQ-Tag method and HPLC on gradient conditions. Seventeen amino acids were analyzed and sixteen amino acids were found in golden mushroom ; fifteen amino acids in pink mushroom respectively. Among total amino acid in golden mushroom, cystein content was the highest and glycine, glutamic acid, proline were followed. Among total amino acid in pink mushroom, cystein was the highest and glycine, lysine, methionine were followed. As shown in Fig.1, 2, concerning amino acids, cystein was dominant. and alanine was detected in golden mushroom and Pleurotus ostreatus sold in market but pink mushroom. Phenylalanine was detected in Pleurotus ostreatus sold in market but that was not detected in golden mushroom and pink mushroom.
