（2S）-3-[5-脱氧-5-（二甲基larsinyl）-β- d -核糖呋喃氧基]-2-羟丙烯-1-磺酸（1a）， 3-[5-脱氧-5-（二甲基larsinyl）-β- d -核糖呋喃氧基]-2-羟基丙烯-1-磺酸（1b）， 1- ‘甘油磷酸’ -2-羟基-3-[5-脱氧-5-（二甲基larsinyl）-β-核糖呋喃氧基]丙烷（1c）， 2-氨基-3-[5-脱氧-5-（二甲基larsinyl）-β- d -核糖呋喃氧基]丙烯-1-磺酸（1d），以及无机砷。其结构主要是用核磁共振光谱法测定的。化合物（1d）此前未见报道。化合物（1b）以一对C-2非对映异构体的形式存在于希兹克菌中。
(2S)-3-[5-Deoxy-5-(dimethylarsinoyl)-β-D-ribofuranosyloxy]-2-hydroxypropyl hydrogen sulphate (1a), 3-[5-deoxy-5-(dimethylarsinoyl)-β-D-ribofuranosyloxy]-2-hydroxypropene-1-sulphonic acid (1b), 1-‘glycerophosphoryl’-2-hydroxy-3-[5-deoxy-5-(dimethylarsinoyl)-β-ribofuranosyloxy]propane (1c), and 2-amino-3-[5-deoxy-5-(dimethylarsinoyl)-β-D-ribofuranosyloxy]propene-1-sulphonic acid (1d), together with inorganic arsenic have been isolated from the edible seaweed Hizikia fusiforme. Structures have been determined chiefly by n.m.r. spectroscopy. Compound (1d) has not been reported previously. Compound (1b) is apparently present in Hizikia as a pair of C-2 diastereoisomers.
