Objective: Study on the flavonoids from the air part of Eupatorium lindleyanum.
Method: Alcohol percolation, silica gel column chromatography and re-crystallization et al.
Result: Jaceosidin, kaempferol, quceritin, astragalin, trifolin and hypersoide were isolated from E. lindleyanum. Their structures were elucidated on the basis of spectral evidence.
Conclusion: Jaceosidin, kaempferol, quceritin, astragalin and trifolin were isolated from E. lindleyanum for the first time.
