Abstract
Chemical investigation of Santolina insularis afforded 11 germacrane sesquiterpenes (1-11), four of which (2, 3, 10, and 11) are new. The stereostructures of these compounds have been established by a combination of spectroscopic techniques (mainly NMR), chemical transformations, and application of the modified Mosher method. Compounds 8 and 10 showed a potent and selective cytotoxic activity against the human colon carcinoma cell line.
