[Comparison of amino acid contents in Panax notoginseng from different habitats].
OBJECTIVE
To determine the contents of amino acid and study the characters of Sanqi (Panax notoginseng) from different habitats.


METHODS
By Hitach 835-50 amino acid anaylzer.


RESULTS
19 amino acid were extracted from root of P. notoginseng. The contents of Arg, Asp, and Glu are high. The beta-Ala and Orn were first separated from P. notoginseng.


CONCLUSIONS
There were differences of the amino acid contents in Sanqi from different habitats. The sequence of its 3 major amino acid contents were Arg > Asp > Glu, which can be considered as a character of Sanqi.
