title: [Studies on chemical constituents of Ligularia altaica].
abstract: OBJECTIVE
  To study the chemical constituents of Lighularia altaica.
  
  
  METHODS
  Various chromatographic techniques were used to isolate and purify the chemical compounds, their structure were elucidated by means of mass, physico-chemical properties and NMR spectral data.
  
  
  RESULTS
  Nine compounds were obtained as: lupeol (1), oleanolic acid (2), 3beta, 16beta-dihydroxy-12-oleanen-28-al (3), ergosterol peroxide (4), stigmasta-7-en-ol (5), 11-hydroxy-10,11-dihydro-euparin (6), 5-hydroxybenzofuran-2(3H) -one- (7), except for beta-sitosterol (8) and daucostrol (9).
  
  
  CONCLUSIONS
  Compounds 3 - 7 are isolated for the first time from this genus, the other compounds are obtained from this plant for the first time.
