[Comparative study on contents of amino acid and major and trace elements in Cornus officinalis before and after being processed].
OBJECTIVE
To investigate amino acid and inorganic element in cornus officinalis and study the effects of processed on contents of them.


METHODS
The amino acid analysis with precolume derivatization was implemented by HPLC and the contents of element in the prevention were determined by ICP.


RESULTS
cornus officinalis contained eighteen inorganic element and abundant K, Ca, Mg. After processed, except for Cu, Ba, Ni, all were increased and the contents of La and Ce were added remarkably. Sixteen amino acid were determined in cornus officinalis and rich asp and glu were measurated. The total content of amino acid decreased, but contents of lys, phe and etc. increased. After processed, the contents of met, his were destroyed and pro reduced, however the total content of amino acid increased.


CONCLUSIONS
cornus officinalis contains many types of amino acid and inorganic element. Processing lead to the dissolved of inorganic element increase and change of contents of amino acid. Plenty K, asp and the increase of the contents of lys, leu, val, and etc. being necessary for mamkind may be one of mechanism of enganced effect on protecting liver and kidney.
