title: [Chemical constituents from stems of Clausena excavata].
abstract: OBJECTIVE
  To study the chemical constituents from the stems of Clausena excavata.
  
  
  METHODS
  The constituents were isolated by various chromatographic techniques(silica gel, RP-MPLC and PHPLC) and their structures were determined on the basis of their spectroscopic data, as well as literatures.
  
  
  RESULTS
  Eleven compounds were separated and identified as adicardin(1),7-[O-α-L-rh-amnopyranosyl-(1-->6)-O-β-D-glucopyranosyloxy]coumarin(2), 6-methoxy-7-[O-α-L-rhamnopyranosyl-(1-->6)-O-β-D-glucopyranosyloxy] coumarin (3), alloisoimperatorin (4), isopentenoyloxypsoralen (5), nordentatin (6), xanthyletin (7), 7-hydroxycoumarin (8), 3-formylcarbazole(9), 3-formyl-6-methoxy carbazole(10), and murrayanine(11).
  
  
  CONCLUSIONS
  compounds 2-4 and 10 are isolated from this plant for the first time, and compounds 1 and 5 are isolated from Clausena genus for the first time.
