title: [Studies on the chemical constituents from the fruit of Aristolochia debilis].
abstract: OBJECTIVE
  To study the chemical constituents of the fruit of Aristolochia debilis.
  
  
  METHODS
  The compounds were isolated by chromatographic techniqcue and crystal methods, the structures were elucidated by spectrum analysis.
  
  
  RESULTS
  8 compounds were isolated from the dry fruit of Aristolochia debilis which were aristolochic acid I (1), aristolochic acid II (2), aristolochic acid III (3), aristolochic acid III a(4), aristolochic acid VII a (5), aristolactam I (6), aristolactam II (7) and aristolactam III a (8).
  
  
  CONCLUSIONS
  Compounds 1-8 are isolated from the fruit of Aristolochia debilis for the first time.
