title: [Studies on chemical constituents in root of Isatis indigotica].
abstract: OBJECTIVE
  To study the chemical constituents in the root of Isatis indigotica.
  
  
  METHODS
  The constituents root were separated through various chromatographic techniques and their structures were elucidated by means of physicochemical properties and the analysis of their spectral data.
  
  
  RESULTS
  Eleven compounds were isolated and identified as (+) -isolariciresinol (1), lariciresinol (2), lariciresinol-9-O-beta-D-glucopyranoside (3), lariciresinol-4'-O-beta-D-glucopyranoside (4), lariciresinol-4,4'-bis-O-beta-D-glucopyranoside (5), 3-formylindole (6), 1-methoxy-3-indolecarbaldehyde (7), 1-methoxy-3-indoleacetonitrile (8), deoxyvasicinone (9), epigoitrin (10), adenosine (11).
  
  
  CONCLUSIONS
  Compounds 4-8 were isolated from I. indigotica for the first time.
