Abstract

Three new sesquiterpenes, 2-deoxy-7-O-methyllemnacarnol (1), 2-deoxy-12α-ethoxy-7-O-methyllemnacarnol (2), and 2-deoxy-12α-methoxy-7-O-methyllemnacarnol (3), were isolated from a soft coral Nephthea sp. collected in Indonesia, together with five known sesquiterpenes. The structures of the new compounds were assigned on the basis of their spectroscopic data.
