title: [Studies on chemical constituents from roots of Peucedanum praeruptorum II].
abstract: OBJECTIVE
  To isolate and identify the chemical constituents from the roots of Peucedantu praeruptorum.
  
  
  METHODS
  The constituents were isolated by column chromatography on silica gel and ODS, and identified by NMR, MS spectroscopic methods.
  
  
  RESULTS
  Eight compounds, (-) sclerodin (1), palmitic acid (2), (+)-praeruptorin E (3), bergapten (4), imperatorin (5), 2,6-dimethyl quinoline (6), tetracosanoic acid (7), and daucosterol (8), were isolated and identified.
  
  
  CONCLUSIONS
  Compounds 1,5-7 were isolated from this plant for the first time.
