title: [Study on chemical constituents from the roots and rhizomes of Sinopodophyllum emodi].
abstract: OBJECTIVE
  To investigate the chemical constituents in the roots and rhizomes of Sinopodophyllum emodi.
  
  
  METHODS
  The compounds were isolated by many different chromatographic methods such as silica gel, Sephadex LH-20, and ODS column. Their structures were identified by their physicochemical properties and spectrascopic data.
  
  
  RESULTS
  Nine compounds were isolated and identified as isopicrodeoxypodophyllotoxin(I), 3beta-hydroxy-7alpha-methoxy-24beta-ethyl-cholest-5-ene(II), 5alpha, 8alpha-epidioxy-(22E,24R)-erg-osta-6,22-dien-3beta-ol(III), 7beta-hydroxysitosterol (IV), beta-sitosterol (V), daucosterol (VI), alpha-glyceryl palmitate (VII), alpha-D-glucose (VIII), 5-hydromethyl furaldehyde (IX).
  
  
  CONCLUSIONS
  Compounds I - IV, VII - IX are obtained from this genus for the first time.
