title: [Chemical Constituents from Sphagneticola trilobata].
abstract: OBJECTIVE
  To study the chemical constituents of the whole plant of Sphagneticola trilobata.
  
  
  METHODS
  The compounds were isolated and purified by column chromatography and their structures were determined by spectroscopic techniques.
  
  
  RESULTS
  Three lignans, two indolics and two phenolic glycosides were isolated from the whole plant of Sphagneticola trilobata and identified as syringaresinol-4-O-β-D-glucopyranoside(1), pinoresinol-4-sulfate(2), pinoresinol-4-O-β-D-glucopyranoside(3), 1H-indole-3-carboxylic acid (4), 1H-indole-3-carbaldehyde(5), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside (6), and 3,5-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside (7).
  
  
  CONCLUSIONS
  Compounds 1 - 7 are isolated from the genus Wedelia for the first time. Compound 4 demonstrates significant inhibitory activity against α-glucosidase.
