title: [A new natural saponin from fruits of Siraitia grosvenorii].
abstract: OBJECTIVE
  To study the chemical constituents in the fruits of Siraitia grosvenorii.
  
  
  METHODS
  Isolation and purification of the constituents were carried out on column chromatography. Their structures were identified by NMR and MS spectral analysis.
  
  
  RESULTS
  Six compounds were isolated and elucidated as mogroside IIIA1 (1), siamenoside I (2), mogroside IVa (3), mogroside IVe (4), mogroside V (5) and 11-oxo-mogroside V(6), respectively.
  
  
  CONCLUSIONS
  Compound 1, mogrol-24-O-beta-D-glucopyranosyl (1 --> 2)-[beta-D-glucopyranosyl(1 --> 6) ]-beta-D-glucopyranoside, was identified as a new natural product from the fruits of S. grosvenorii.
