title: [A new monoterpene glycoside from Paeonia lactiflora Pall].
abstract: OBJECTIVE
  To study the chemical constituents of Paeonia lactiflora.
  
  
  METHODS
  The constituents of P. lactiflora were separated by using various kinds of modern chromatography and was identified its structure on the basis of spectral analysis.
  
  
  RESULTS
  A monoterpene glucoside named albiflorin R1 was isolated from the roots of Paeonia lactiflora Pall. In the structure of albiflorin R1, the aglycone connected with a glucose at its 2-OH while the hemiacetal hydroxyl in glucose moiety was free.
  
  
  CONCLUSIONS
  Albiflorin R1 is a new monoterpene glycoside.
