Deskripsi
Two new cembrane diterpenes, sicrassarines A and B (compounds <strong>1</strong> and <strong>2</strong>), were isolated from the Taiwanese soft coral <em>Sinularia crassa</em>. The structures of the new metabolites were determined on the basis of extensive spectroscopic analysis, particularly mass spectroscopy and 2D NMR (<sup>1</sup>H–<sup>1</sup>H COSY, HMQC, HMBC, and NOESY) spectroscopy.
