Abstract: A novel marine C30-sterol clavisterol Awith an interesting cyclopropane moiety side chain, was isolated from the Chinese soft coral Clavularia viridis collected from Xisha Islands in the South China Sea. The crude methanol-CHCl3(10:1) extract was chromatographed to obtain the crude clavis-terol Afrom the cyclohexane (9%) ethyl acetate eluting portion. Pure clavisterol Ais a needle crystal, m.p. 158-160℃ (from acetone/p. ether), [A]D20-2.5(CHCl3, C, 0.0233), molecular formula C30H50O, (HRMS, M+426. 3862). From the IR, MS, NMR data and comparing the data with those of cholesterol and stoloniferone-d, the structure of clavisterol Awas designed as 1.
