title: [Studies on chemical constituents from fruits of Paliurus ramosissimus].
abstract: OBJECTIVE
  To study the chemical constituents from the fruits of Paliurus ramosissimus.
  
  
  METHODS
  The constituents of P. ramosissimus were separated with various chromatographic techniques and their structures were elucidated by means of spectral analysis and physico-chemical properties.
  
  
  RESULTS
  Nine compounds were isolated and identified as umbelliferone (1), scoparone (2), aurapten (3), bergapten (4), isopimpinellin (5), byakangelicin (6), xanthotoxol (7), isosakuranin (8), poncirin (9).
  
  
  CONCLUSIONS
  Compounds 1-9 were isolated from the fruits of P. ramosissimus for the first time.
