Our continued investigation on the South China Sea gorgonian Dichotella gemmacea led to the isolation of 16 new briarane-type diterpenoids, dichotellides F–U (1–16), along with 18 known analogues (17–34). Their structures were determined by MS, 1D and

Seven new briarane diterpenoids, gemmacolides AS-AY (1–7), were isolated together with ten known analogues (8–17) from the South China Sea gorgonian Dichotella gemmacea. The structures of the new compounds were elucidated by the detailed analysis of spectroscopic

One new briarane-type diterpenoid, dichotellide V (1), along with four known analogues, gemmacolide N (2), dichotellide J (3), junceelin A (4) and junceellolide A (5), was isolated from the South China Sea gorgonian Dichotella gemmacea. All of the isolated

Objective: To study the chemical constituents from Dichotella gemmacea. Methods: Chemical constituents were isolated by silica gel and Sephadex LH-20 column chromatography. The structures of the isolated compounds were elucidated through spectroscopic
