Bioactivity-guided fractionation of antileishmanial active CH2Cl2 phase of MeOH extract from leaves of Calea pinnatifida led to isolation of two sesquiterpene lactones calein C (1) and calealactone C (2), which structures were stablished on the basis of spectroscopic analysis. Compounds 1 and 2
This work describes the chromatographic fractionation of the aerial parts of Calea pinnatifida and the structural characterization and determination of the absolute configuration of the isolated compounds as well as their antitumor potential. The HPLC fractionation of the
