| Abstract: |
| Contents of amino acids in the different parts of Nitraria sibirica Pall. and Nitraria tangutorum Bobr. were determined and their nutritional evaluation were also carried out. Nitraria species were rich in proteins with 18 amino acids, 8 of which were essential for human nutrition. The content of essential amino acids in Nitraria juice was much higher than that in Hippophae rhamnoides juice. The distribution of proteins and amino acids were similar in the different parts of the two Nitraria species. but first limiting amino acids were somewhat varied. |
