title: [Studies on the chemical constituents of Gueldenstaedtia stenophylla].
abstract: OBJECTIVE
  To study the chemical constituents of Gueldenstaeditia stenophylla.
  
  
  METHODS
  The constituents were isolated by alcohol extraction, column chromatography on silica gel. Their structures were elucidated by chemical and spectroscopic methods.
  
  
  RESULTS
  Six compounds were obtained, and five of them were identified as n-hexadecanioc acid (I), beta-sitosterol (II), daucosterol (III), apigenin (IV), D-fructose (VI). Compound V was being determined.
  
  
  CONCLUSIONS
  Five compounds are isolated from Gueldenstaedtia stenophylla and compounds I, III are extracted from Gueldenstaedtia Fisch for the first time.
