title: Sinensioside A, a new sesquilignan glycoside from Selaginella sinensis.
abstract: OBJECTIVE
  To investigate the chemical constituents of Selaginella sinensis (Desv.) Spring.
  
  
  METHODS
  Chromatographic separations on Diaion HP-20, silica gel, and Sephadex LH-20 were used. The structures of the isolates were elucidated on the basis of spectroscopic analysis, as well as chemical methods.
  
  
  RESULTS
  Eight compounds were obtained and their structures were identified as sinensioside A (1), syringaresinol-4- O-β-D-glucopyranoside (2), (+)-medioresinol-4-O-β-D-glucopyranoside (3), pinoresinol-4, 4'-di-O-β-D-glucopyranoside (4), quercetin (5), eucomic acid (6), shikimic acid (7), and 2, 3-dihydroamentoflavone (8).
  
  
  CONCLUSIONS
  Compound 1 is a new dihydrobenzofuran sesquilignan glycoside from Selaginella sinensis.
