title: [Studies on chemical constituents from leaves of Securinega suffruticosa].
abstract: OBJECTIVE
  To investigate the chemical constituents of Securinega suffruticosa.
  
  
  METHODS
  It was isolated and purified by silica gel chromatography. Their structures were elucidated by means of spectral analysis.
  
  
  RESULTS
  Four compounds were isolated and identified as ent-phyllanthidine (1), virosecurinine (2), 14,15-dihydrovirosecurinine (3) and viroallosecurinine (4).
  
  
  CONCLUSIONS
  All of four compounds were isolated from S. suffruticosa for the first time and were the enantiomers isolated from this plant before.
