title: [Study on chemical constituents of Smallanthus sonchifolius].
abstract: OBJECTIVE
  To study the chemical constituents of Smallanthus sonchifolius.
  
  
  METHODS
  Chemical constituents were separated through chromatographic methods and their structures were elucidated by spectral analysis.
  
  
  RESULTS
  Seven compounds were isolated from the chloroform fraction of 75% alcohol extract from the leaves of Smallanthus sonchifolius. Their structures were elucidated as gallic acid (1), beta-sitosterol (2), behenic acid (3), Kaempferol (4), Quercetin (5), vanillic acid (6), hexadecanoic acid (7).
  
  
  CONCLUSIONS
  Compounds 1, 4, 6 and 7 are isolated from this plant for the first time.
