title: [Studies on chemical constituents in rhizome of Elaeagnus bockii I].
abstract: OBJECTIVE
  To study the chemical constituents in the rhizome of Elaeagnus bockii.
  
  
  METHODS
  Compounds were isolated by silica gel and Sephadex LH-20 chromatography. Their structures were elucidated by means of spectral analysis.
  
  
  RESULTS
  Seven compounds were isolated from the rhizomes of E. bockii, and their structures were identified as angelicin (1), psoralen (2), vanillic acid (3), bakuchiol (4), oleanolic acid (5), ursolic acid (6) and beta-sitosterol (7 ).
  
  
  CONCLUSIONS
  All these compounds were obtained from E. bockii for the first time.
