title: [Studies on the chemical constituents of Rubus parvifolius].
abstract: OBJECTIVE
  To study the chemical constituents of Rubus parvifoliu.
  
  
  METHODS
  The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis such as 1H-NMR, 13C-NMR, FT-IR, et al.
  
  
  RESULTS
  Seven compounds were isolated from the roots of Rubus parvifolius L., they were identified as p-sitosterol (I), lauric acid (II), O-nitrophenol (III), beta-daucosterol (IV), euscaphic acid (V), camelliagenin A (VI) and(+) -catech in (VII).
  
  
  CONCLUSIONS
  Compounds III and VII are isolated from the plant for the first time.
