一种与2,3,4-三- o -甲基-6-脱氧α -甘露苷相连的新型16元环内酯，lyngbyaloside(1)，已从采集于巴布亚新几内亚莱因岛的蓝绿藻Lyngbya bouillonii中分离出来。其结构已通过详细的高场二维核磁共振研究确定。通过NOE差异实验分析，提出了13个碳原子中8个的相对构型。
A novel 16-membered macrolide linked to a 2,3,4-tri-O-methyl-6-deoxy-alpha-mannopyranoside, lyngbyaloside (1), has been isolated from the blue-green alga Lyngbya bouillonii, collected on Laing Island (Papua New Guinea). Its structure has been established by a detailed high-field 2D NMR study. The relative configuration of 8 out of the 13 stereogenic carbon atoms is proposed from the analysis of NOE difference experiments.
