Isolation of Lobane and Prenyleudesmane Diterpenoids from the Soft Coral .

Further chemical investigation of the EtOAc extract of the soft coral resulted in the discovery of eleven new diterpenoids lobovarols F-P (-) of lobane- and prenyleudesmane-types, along with two known metabolites ( and ). The structures of the new metabolites were established by spectroscopic analyses, including 2D NMR experiments. The absolute configuration of was determined using Mosher's method.
