title: [Studies on the chemical constituents from the roots and rhizomes of Gerbera piloselloides].
abstract: OBJECTIVE
  To study the chemical constituents from the roots and rhizomes of Gerbera piloselloides.
  
  
  METHODS
  The compounds were isolated by silica gel column chromatography, and their structures were elucidated by means of spectral analysis.
  
  
  RESULTS
  Seven compounds were identified as bothrioclinin (I), hydroquinone (II), marmesin (III), succinic acid (IV), umbelliferone (V), isoarborinol (VI) and beta-sitosterol (VII).
  
  
  CONCLUSIONS
  Compound I, V and VI were isolated from Gerbera genus for the first time.
