title: [Water-soluble constituents from roots of Capparis tenera].
abstract: OBJECTIVE
  To study the chemical constituents of the roots of Capparis tenera.
  
  
  METHODS
  The chemical constituents were isolated and repeatedly purified by kinds of column chromatography and the structures were elucidated by the NMR spectra and physicochemical properties.
  
  
  RESULTS
  Eight compounds were isolated and identified as erigeside C (1), glucosuringic acid (2), vanillic acid 4-O-beta-D-glucoside (3-methoxy 4-glucosyl-benzoic acid) (3), 4-O-beta-D-glucopyranosylbenzoate (4), 3', 5'-dimethoxy- 4-O-beta-D-glucopyranosyl-cinnamic acid (5), tachioside (6), 2, 3-dihydroxy-1-(4-hydroxyl-3, 5-dimethoxyphenyl)-1-propanone (7) and acacetin 7-rutinoside (8).
  
  
  CONCLUSIONS
  Compounds 1-8 were all isolated from this plant for the first time and the compound 8 was isolated from this gene for the first time.
