title: [The isolation and identification of a new lignanoside from Selaginella tamariscina (Beauv.) Spring].
abstract: OBJECTIVE
  To study the chemical constituents of Selaginella tamariscina (Beauv.) Spring.
  
  
  METHODS
  The compounds were isolated and purified by macroporous adsorption resin, Sephadex LH-20 and silica gel column chromatography and identified on the basis of their physicochemical and spectral data.
  
  
  RESULTS
  Four compounds were obtained from the n-BuOH fraction of 70% acetone extracts. Their structures were elucidated as (7S, 8R)-7, 8-dihydro-7-(4-hydroxy-3,5-dimethoxyphenyl)-8-hydroxymethyl-[1'-( 7'-hydroxyethyl)-5' methoxyl] benzofuran-4-O-beta-D-glucopyranoside (tamariscinoside C, I), D-mannitol (II), tyrosine (II), shikimic acid (IV).
  
  
  CONCLUSIONS
  Compound I is a new compound, compounds II and III were obtained from the genius for the first time, compound IV was yielded from the plant for the first time.
