Three new δ-elemanolide-type sesquiterpene lactones, zinagrandinolides A-C (1-3), and the known δ-elemanolide 4 have been isolated by a bioassay-guided fractionation of a cytotoxic hexane extract of the aerial parts of Zinnia grandiflora. The structures of 1-3 were determined on the basis of high-resolution mass and NMR data. All compounds exhibited strong cytotoxicity against the cancer cell lines NCI-H460, MCF-7, SF-268, and MIA Pa Ca-2 and the normal human fibroblast cell type WI-38, but none showed significant selectivity.
