Further casbane-type diterpenes from the soft coral Sinularia depressa

摘要： AIM: To study the minor diterpenes from the soft coral Sinularia depressa. METHOD: The chemical constituents were isolated and purified by various chromatographic techniques, and the chemical structures, including absolute configuration, were established on the basis of detailed analysis of spectroscopic data and by literature comparison with the data of related known compounds. RESULTS: A new casbane-type diterpene, 2-epi-10-hydroxydepressin(1), was isolated and identified. CONCLUSION: Compound 1 is a new casbane-type diterpene. ... （共4页）
