(Asteraceae) has been used for a long time for medicinal purposes due to its various pharmacological effects and richness in active compounds such as phenolics, sesquiterpenes, pyrrolizidine alkaloids, and polysaccharides. Despite the high content of compounds that have important roles in medicinal plants, there are still limited literature data regarding this valuable species. The plant was fractioned using chloroform (EC) and distilled water (EA) and HPLC analysis revealed the presence of eupatorin, eupatilin, and quercetin in EC and caffeic acid and rutin in EA. The antiproliferative potential on BT-20, HepG2, Caco-2, and Jurkat cancer cell lines was assessed by MTS test. Jurkat cells were more sensitive to both extracts (IC50 of ± for EC and ± µg/mL for EA), while the other lines were susceptible only to EC (IC50 ± on Caco-2 cells and over 100 µg/mL on BT20 and HepG2 cells) after 24 h
