OBJECTIVE
To study the chemical constituents from Carpesium abrotanoides.
METHODS
Compounds were isolated and pu- rified by silica gel and Sephadex LH-20 column chromatography, their structures were determined by using spectroscopic analysis.
RESULTS
Ten compounds were isolated and identified as

We investigated the function and molecular mechanisms of 2-desoxy-4β-propylcarbamate-pulchellin (P-13), a sesquiterpene lactone derivative of 2-desoxy-4-epi-pulchellin from the traditional Chinese medicinal herb Carpesium abrotanoides L, in regulating STAT3 signaling and cancer cell growth. We found
