A promising anticancer and antimalarial component from the leaves of Bidens pilosa.

Bidens pilosa is used in folk medicine for various applications due to the presence of polyacetylenes, flavonoids, terpenoids, phenylpropanoids and others. Bioactivity-guided fractionation of different extracts of B. pilosa leaf showed potential in vitro anticancer and antimalarial activity and led to the identification of a potential marker compound, phenyl-1,3,5-heptatriyne. Erythrocyte osmotic fragility experiments revealed the various extracts as well as the marker component's toxicity profiles on normal blood cells.
