Abstract
A new cembrane-type diterpenoid, named iso-ximaonanolobatin G (1), and one known related one, namely ximaonanolobatin G (2), along with four known steroids, were isolated from the South China Sea soft coral Sinularia nanolobata. Their full structures were elucidated by extensive spectroscopic analysis, quantum mechanical (QM)-NMR methods, and by the comparison of the spectroscopic data with those reported in the literature.
