Four new diterpenoids, casearoids A~D (1~4), including dolabrane, orosane, labdane, and cembrane, were isolated and characterized from Microdesmis casearifolia. Their structures were elucidated by extensive spectroscopic data analysis. The absolute configurations of these diterpenoids were established by analysis of the electronic circular dichroism (ECD) data.
