Isotenulin

Isotenulin

Isotenulin, C17H22O5, is a sesquiterpene lactone isolated from sneezeweed Helenium amarum. It crystallizes with two independent molecules in the asymmetric unit. In each molecule, two five-membered rings (cyclopentenone and lactone) are trans-fused to the central seven-membered ring. The five-member...
