title: [Chemical constituents in whole herb of Bidens pilosa var. radiata].
abstract: OBJECTIVE
  To study the chemical constituents of Bidens pilosa var. radiata.
  
  
  METHODS
  The constituents were separated and purified with silica gel column, and identified by physicochemical properties and spectral methods.
  
  
  RESULTS
  Ten compounds were separated and identified as friedelin (1), n-tridecane (2), friedelinol (3), beta-sitosterol (4), 21 a-hydroxyfriedelan-3-one (5), stigmasterol (6), lupeol (7), stigmasterol-3-O-beta-D-glucopyranoside (8), eleosanole acid (9), friedelin-3beta-ol-27-oic acid (10).
  
  
  CONCLUSIONS
  Ten compounds are isolated from this plant for the first time.
