title: [Studies on chemical constituents from the root of Polygonatum kingianum].
abstract: OBJECTIVE
  To investigate the anti-HIV constituents from the root of Polygonatum kingianum.
  
  
  METHODS
  The compounds were isolated by column chromatography on silica gel, Sephadex LH-20, MCI-gel CHP-20P and their structures were determined on the basis of their spectroscopic evidence including IR, MS and NMR data.
  
  
  RESULTS
  13 compounds were isolated, of which nine compounds were identified as liquiritigenin, isoliquiritigenin, 4', 7-dihydroxy-3'-methoxyisoflavone, (6aR, 11aR)-10-hydroxy-3, 9-dimethoxypterocarpan, 5-hydroxymethyl-2-furancarboxaldehyde, salicylic acid, n-butyl-beta-D-fructopyranoside, n-butyl-beta-D-fructofuranoside, n-butyl-alpha-D-fructofuranoside.
  
  
  CONCLUSIONS
  Compounds 1-6 were obtained from this plant for the first time.
