title: [Chemical constituents contained in aerial parts of Emilia sonchifolia].
abstract: OBJECTIVE
  To study the chemical constituents contained in ethanol extracts from aerial parts of Emilia sonchifolia.
  
  
  METHODS
  The compounds were separated and purified with various chromatographic techniques, and their structures were identified on the basis of physicochemical properties and spectral data.
  
  
  RESULTS
  Fifteen compounds were separated from ethyl acetate fraction of 90% ethanolic extract and identified as rhamnetin (1), isorhamnetin (2), quercetin (3), luteolin (4), tricin-7-O-beta-D-glucopyranoside (5), 8-(2"-pyrrolidinone-5"-yl) -quercetin (6), 5, -2', 6'-trihydroxy-7, 8-dimethoxyflavone-2'-O-beta-D-glucopyranoside (7), succinic acid (8), fumaric acid (9), p-hydroxybenzoic acid (10), 4-hydroxy isophthalic acid (11), 3, 4-dihydroxycinnamic acid (12), esculetin (13), isowedelolactone (14) and uracil (15), respectively.
  
  
  CONCLUSIONS
  All compounds except compound 3 were separated from this genus for the first time.
