title: [Comparison of amino acid contents in Panax notoginseng from different habitats].
abstract: 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.
