title: [Studies on the triterpenoids constituents from Phyllodium elegans].
abstract: OBJECTIVE
  To study the chemical constituents of Phyllodium elegans.
  
  
  METHODS
  The compounds were isolated and purified by extraction, chromatography on silica gel and recrystallization. Their structures were elucidated on the basis of physicochemical properties and spectra analysis.
  
  
  RESULTS
  Three triterpenoids were isolated and identified as lupenone (1), lupeol (2), betulin (3).
  
  
  CONCLUSIONS
  Compound 2 is obtained from the genus for the first time, Compounds 1-3 are isolated from this plant for the first time.
