title: [The new secondary metabolite from Polygonatum odoratum].
abstract: OBJECTIVE
  To investigate the chemical constituents of Polygonatum odoratum.
  
  
  METHODS
  Silica gel column chromatography was used to separate and purify the chemical constituents. The structures were elucidated by chemical and spectral analysis.
  
  
  RESULTS
  One dipeptide and one furostanol glycoside were isolated from the rhizomes of P. odoratum, and their structures were identified as O-acetate of N (N-benzoyl-S-phenylalaninyl)-S-phenylalaninol (1) and 22-hydroxy-25 (R and S)-furost-5-en-12-on-3beta,22,26-triol 26-O-beta-D-glucopyranoside (2), respectively.
  
  
  CONCLUSIONS
  Compound (2) is a new compound and is first reported to be of the furostanol monoglycoside glycosylated at C-26.
