Twenty one arsenolipids, including eight new compounds (AsSugPL 692, AsSugPL 706, AsSugPL 720, AsSugPL 734, AsSugPL 742, AsSugPL 746, AsSugPL 748, and AsSugPL 776) were identified in the edible brown alga Kombu, Saccharina japonica, by means of HPLC coupled with elemental and molecular mass spectrometry. The hitherto undescribed compounds are all mono-acyl arsenosugar phospholipids, differing from previously reported natural arsenic-containing phospholipids by containing only one fatty acid on the glycerol group. Collectively, this new group of mono-acyl compounds constituted about 30% of total lipid arsenic; other significant groups were the di-acyl arsenosugar phospholipids (50%) and arsenic hydrocarbons (20%). The origin and relevance of the mono-acyl arsenosugar phospholipids in Kombu, a commercial seafood product, is briefly discussed.
通过高效液相色谱结合元素和分子质谱法，在可食用褐藻海带（Saccharina japonica）中鉴定出21种砷脂，其中包括8种新化合物（AsSugPL 692、AsSugPL 706、AsSugPL 720、AsSugPL 734、AsSugPL 742、AsSugPL 746、AsSugPL 748和AsSugPL 776）。这些迄今未描述的化合物均为单酰基砷糖磷脂，与先前报道的天然含砷磷脂不同，其甘油基团上仅含一个脂肪酸。总体而言，这组新的单酰基化合物约占总脂质砷的30%；其他主要类别为二酰基砷糖磷脂（50%）和砷烃（20%）。本文简要讨论了商业海产品海带中单酰基砷糖磷脂的来源及相关性。
