Abstract: The genus of Laurencia has been well known for its production of terpenes and C15acetogenins, which are usually halogenated. Anew iodolactone (1) was isolated from the ethanol extract of the alga Laurencia majuscula, collected from the Xisha Islands in the South China Sea. Compound 1 is a kind of white solid, m. p. 63-64℃. The molecular for-mula was established by HREIMSas C26H47O4I. Generally, chlorinated or brominated metabolites are common in marine organisms. In contrast, iodosubstituted compounds are quite rare and interesting. The structure of 1 was elucidated by the spectral analysis, having a 3-iodo-δ-lactone structure moiety. Besides, two known compounds, cholesterol and n-e-icosanoic acid, were obtained as well.

Key words: Alga, Laurencia majuscula, Iodolactone
