Ten sesquiterpenes, together with 12 known compounds were isolated from leaves of Laurus nobilis L. Based on spectroscopic analyses, the 10 compounds were determined to be eudesmane lactones and their corresponding methyl esters. Most of these compounds exhibited moderate-to-significant cytotoxicity towards K562 leukemia cells. One compound had a higher cytotoxicity than doxorubicin, while other compounds had moderate to no activity
