Fifteen new guaiazulene-based terpenoids designated anthogorgienes A-O (1-15) were isolated from a Chinese gorgonian Anthogorgia sp., together with eight known analogues (16-23). The structural patterns were classified into monomers, dimers, and trimers,

Two new guaiazulene-based analogues, ochracenoids A (1) and B (2), along with four known analogues (3-6), were isolated from the gorgonian Anthogorgia ochracea collected from the South China Sea. The planar structures of the new compounds were elucidated

Chemical examination of a Chinese gorgonian Anthogorgia sp. resulted in the isolation of seven terpenoids, including two new compounds, an rearranged serrulatane-type diterpenoid anthogorgiene P (1) and a guaiazuene-based terpenoid anthogorgiene Q (2).

Objective: To study the chemical constituents of Anthogorgia sp. collected from Beihai area of Guangxi Zhuang Autonomous Region, China. Methods The Et 2O extract of Anthogorgia sp. was subjected to repeated silica gel (eluted with Pe: Ac=99:1, 49:1,
