title: [Chemical study on ethyl acetate soluble portion of Kadsura oblongifolia].
abstract: OBJECTIVE
  To study the chemical constituents in the stems of Kadsura oblongifolia.
  
  
  METHODS
  The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.
  
  
  RESULTS
  Seven compounds named kaempferol-3-O-alpha-L-arabinofuranoside (1), kaempferol-3-O-alpha-D-arabinopyranoside (2), quercetin-3-O-alpha-D-arabinopyranoside (3), quercetin-3-O-alpha- L-arabinofuranoside (4), quercetin-3-O-beta-D-glucopyranoside (5), quercetin (6), kaempferol (7) were isolated and identified.
  
  
  CONCLUSIONS
  Compounds 1-7 were obtained from this plant for the first time. Compounds 1-4 were isolated from Schisandraceae family for the first time.
