title: [Studies on the diterpenoids of Wedelia prostrata].
abstract: OBJECTIVE
  To study the chemical constituents of Wedelia prostrata.
  
  
  METHODS
  Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.
  
  
  RESULTS
  Seven compounds were obtained and identified as ent-kaur-16-en-19-oic acid (I), ent-kaur-16alpha, 17-dihydroxy-19-oic acid (II), ent-kaur-15alpha-senecioyloxy-16-en-19-oic acid (III), beta-sitosterol (IV), stigmasterol (V), stigmasterol-3-O-beta-D-glucopyranoside (VI) and n-hexacosanol (VII).
  
  
  CONCLUSIONS
  Compounds I-III are isolated from this plant for the first time.
