Chemical investigation on the nonpolar extract of the Brazilian brown alga Canistrocarpus cervicornis (Dictyotaceae) has led to the isolation of a new diterpene 1 and four known seco ‐dolastane diterpenes 2 – 5 . Their chemical structures were elucidated by 1D‐ and 2D‐NMR spectroscopy, and the data was compared with the literature. A full X‐ray diffraction analysis confirmed the absolute configuration of 1 .
