A reinvestigation of Euphorbia decipiens with a modified extraction procedure resulted in the isolation and structure elucidation of eight new myrsinane‐type diterpene esters (see 3 – 10 ). Moreover, revised structures are proposed for decipinone B ( 1 ) and C ( 2 ) on the basis of X‐ray‐diffraction analyses. The structures of the compounds were elucidated by means of different spectroscopic methods, including 1D‐ and 2D‐NMR studies.
