从红藻 Laurencia okamurai 中分离出四种新的铜烯衍生倍半萜，即月桂过氧化物 (1)、10-溴异海藻素 (2)、异去溴月桂醇 (3) 和 10-羟基异月桂烯 (4)，以及七种已知的相关倍半萜 (5-11)。它们的结构是在详细的光谱分析和与已知化合物的比较的基础上确定的。化合物 8-11 首次被证明代表真正的天然产物，并且首次报道了 5 的完整 1H-和 13C-NMR 归属。
Four new cuparene-derived sesquiterpenes, laureperoxide (1), 10-bromoisoaplysin (2), isodebromolaurinterol (3), and 10-hydroxyisolaurene (4), together with seven known, related sesquiterpenes, 5–11, have been isolated from the red alga Laurencia okamurai. Their structures were determined on the basis of detailed spectroscopic analyses and comparison with known compounds. Compounds 8–11 were shown for the first time to represent true natural products, and the full 1H- and 13C-NMR assignments of 5 are reported for the first time.
