Abstract
A novel brominated cuparene-derived sesquiterpene ether, 8,10-dibromo-3,7-epoxy-laur-13-ol (1), was isolated from Laurencia sp. collected in South China Sea. Besides this, two known sesquiterpenes, (9β)-aristol-1(10)-en-9-ol (2) and aristolone (3), were also yielded, and aristolone (3) was obtained from Laurencia for the first time. Their structures were elucidated by spectroscopic methods.
