Objective: To investigate the amino acids from the fruit of Clausenae lansium.
Methods: To determine the content of hydrolyzed and free amino acids from fresh fruit and dried fruit of Clausenae lansium by HPLC, 10 mmol/L Na2HPO4 (PB) was used as mobile phase (A) and PB-methanol-acetic acid (50:35:15) was used as mobile phase (B) on a Hypersil ODS column.
Results: 16 kinds of amino acids were assayed, 10 of all was necessary or half-necessary amino acids. The total content of free and hydrolyzed amino was 4.8 mg/g and 15.0 mg/g in fresh fruit; 4.8 mg/g and 15.0 mg/g in dried fruit.
Conclusion: There are abundant amino acids in the fruit of Clausenae lansium.
