title: [Chemical Constituents from Cynanchum paniculatum].
abstract: OBJECTIVE
  To investigate the chemical constituents from Gynanchum paniculatum.
  
  
  METHODS
  The constituents were isolated and purified by silica gel, Sephadex LH-20 column chromatography, and preparative TLC. Their structures were identified on the basis of spectral data and physiochemical characteristics.
  
  
  RESULTS
  15 compounds were isolated from 70% ethanol extract and identified as β-sitosterol(1), β-daucosterin (2), mudanoside A (3), paeonolide (4), santamarin (5), paeonol(6), annobraine (7), laricircsinol (8), α-asarone(9), 7-angelyheliotridine(10), β-amyrin(11), uridine(12), kaempferol-3-O-β-D-glucopyranosyl(1→2)α-L-arabinopyranoside(13), kaempferol-7-O-(4", 6"-di-p-hydroxycinnamoyl-2", 3"-diacetyl)-β-D-glucopyranoside(14), and (2S, E)-N-[2-hydroxy-2-(4-hydroxyphenyl) ethyl] ferulamide (15).
  
  
  CONCLUSIONS
  Compounds 4, 6, 8, 11, 12 and 15 are isolated from this plant for the first time, compounds 5 and 14 are firstly isolated from the palnts of Cynanchum genus.
