title: [Studies on chemical constituents of effective part of Gastrodia elata].
abstract: OBJECTIVE
  To study the chemical constituents of effective part of Gastrodia elata.
  
  
  METHODS
  The constituens were isolated by column chromatographies with silica gel and ODS, and identified by NMR, MS spectra.
  
  
  RESULTS
  Six compounds were isolated and identified.
  
  
  CONCLUSIONS
  Three compounds were isolated from this plant for the first time.
