title: [Triterpenoids from Leaves of Ilex latifolia].
abstract: OBJECTIVE
  To investigate the chemical constituents from the leaves of Ilex latifolia.
  
  
  METHODS
  The constituents were iso- lated and purified by various chromatographic techniques. Their structures were identified by UV, IR, MS and NMR spectroscopic analy- sis.
  
  
  RESULTS
  Ten compounds were isolated from the leaves of flex latifolia. Their structures were respectively identified as 3β,13β-Di- hydroxy-urs-11-en-28-oic acid-13-lactone (1), β-sitosterol (2) 3-hydroxy-11-oxours-12-ene (3), (20S,24S)-epoxydammarane-3β,25- diol (4), 25-deuteriostigmasterol (5), α-amyrin (6), foliasalacin A4 (7), 23-hydroxyursolic acid (8), p-coumaric acid (9) and β-dau- costerol (10).
  
  
  CONCLUSIONS
  Compounds 1,3-5,7 and 9 are isolated from this plant for the first time.
