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.
Conclusion:
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.
