Abstract:Amino acid is the main component of vegetable taste，the composition and content of amino acid are closely related to the quality of vegetable.In order to better develop Musa balbisiana resources，in this study，precolumn derivatization-high performance liquid chromatography was used to determine the composition of hydrolysis amino acids in its stem，flower and bracts.The results showed that the three parts of Musa balbisiana contained 18 kinds of amino acids，the total content of amino acids was more than 33 mg/g，and the total content of amino acids in the bracts was the highest.Three parts of Musa balbisiana all included 8 essential amino acids，and the proportion of essential amino was more than 37%.The total content of sweet amino acids and delicious amino acids in three parts of wild banana was much higher than the content of bitter amino acids，and the proportion of drug-effectives amino acids was more than 70%.Musa balbisiana is rich in amino acids and can be used as a new resource for food development.
