Publication date: August 2018Source: Biochemical Systematics and Ecology, Volume 79Author(s): Xin-Xin Yang, Yong-Zheng Su, Ji Tan, Chun-Er Cai, Pei-Min He, Rui JiaAbstractA new Bis-sesquiterpene, Nanji A (1), has been isolated together with 7 known compounds, debromolaurinterol (2), laurinterol (3), laurinterol acetate (4), isolaurinterol (5), 3α-hydroperoxy-3-epiaplysin (6), 3β-hydroperoxyaplysin (7), Laurokomurenene A (8), from the Nanji red alga Laurencia okamurai. The structure of 1 was elucidated on the basis of extensive spectroscopic analysis of its EIMS, 1D and 2D NMR data. Furthermore, the chemotaxonomic significance of these compounds was also summarized.
