“…ligulatus ). Previously, we described the isolation and structural characterization of five new dolastanes, one new 2,6- cyclo -xenicane, twenty new dolabellanes, two diterpenes featuring novel carbon skeletons, and several known compounds [3,4,5,6,7]. Herein, we report the isolation and structure elucidation of three new dolastanes ( 1 – 3 ) and five known perhydroazulene diterpenes.…”
