[Study on amino acids from the fruit of Clausena lansium].
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.


CONCLUSIONS
There are abundant amino acids in the fruit of Clausenae lansium.
