Mono-acyl arsenosugar phospholipids in the edible brown alga Kombu (Saccharina japonica)
چکیده انگلیسی


- Twenty one arsenolipids were identified in the brown alga Kombu.
- Eight new arsenolipids comprised an arsenosugar bound into mono-acyl phospholipids.
- The new compounds were also in fresh Kombu, suggesting they are natural constituents.

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.
