Abstract A chemical investigation of Tithonia rotundifolia afforded seven new sesquiterpenelactones in addition to three known ones. The structures of the new compounds 3-acetyl-15-hydroxyleptocarpin, 15-hydroxyleptocarpin and tirotundifolins A, B, C, D and E were established by spectroscopic and chemical means.
