title: Terpenoids from Ligularia kangtingensis.
abstract: BACKGROUND
  Ligularia kangtingensis, a species from the genus Ligularia (Compositae), is an indigenous plant in Southwest China and more than 20 species in this genus have been used as folk medicines in China.
  
  
  OBJECTIVE
  The chemical constituents of the whole plant of L. kangtingensis were studied.
  
  
  METHODS
  The dried whole plants were extracted with ethanol. Its chemical constituents were mainly isolated and purified by silica gel and Sephadex LH-20 column chromatography and their structures were identified on the basis of spectral analysis.
  
  
  RESULTS
  Twelve known terpenoids, including two monoterpenoids, five sesquiterpenoids and five triterpenoids, were isolated and identified from the whole plant of L. kangtingensis.
  
  
  CONCLUSIONS
  All of the 12 known compounds were isolated for the first time from L. kangtingensis.
