Abstract Two diterpenoids with a novel carbon skeleton were isolated from the neutral fraction of Halimiumviscosum together with another with a tormesane skeleton. The structures of two of them were determined by chemical transformation of tormesol and by spectroscopic methods, including 1 H- 13 C normal and long-range two dimensional correlation experiments.
