title: [The determination of three effective constituents in wild and cultivated Gastrodia elata from Bomi].
abstract: OBJECTIVE
  To determine the contents of gastrodin, amino acids and total flavonoids in wild and cultivated Gastrodia elata, in order to choose the best method for its cultivation. The Gastrodia elata was picked at Guxiang town Bomi county Linzhi Region in Tibet.
  
  
  METHODS
  HPLC was used to determine the content of gastrodin. The autoanalyzer was used to determine the content of amino acid. The ultraviolet spectrophotometer was adopted to measure the content of total flavonoids.
  
  
  RESULTS
  The Gastrodin in wild Gastrodia elata was the highest. The contents of amino acids and total flavonoids in organic cultivated Gastrodia elata were higher than those in common cultivated and wild Gastrodia elata.
  
  
  CONCLUSIONS
  The organic cultivated Gastrodia elata has better quality.
