text: Naturally occurring alcohol derivatives of capnellene have been isolated using simple acetone extraction from Capnella imbricata, a species of soft coral (order Alcyonacea) known as Kenya Tree Coral. Capnella is a widely distributed genus of soft coral, found primarily in the tropical reefs of Indonesia.   These corals produce a variety of sterols, sesquiterpenes and diterpenes. Specifically, the capnellanol derivatives found in Capnella serve as a defense system by inhibiting the growth of microorganisms and the settlement of larvae on the coral’s surface.  However, the details of this defense mechanism have not been extensively explored. Although the natural synthesis of capnellene and its derivatives is not yet understood, the sesquiterpene hydrocarbon precapnelladiene has been isolated from the same coral and research suggests that may be a biogenetic precursor.
