Abstract
This study describes the identification and quantification of five new arsenolipids present in raw marine fish oil extracted mainly from Peruvian anchoveta (Engraulis ringens).
Highlights
In recent years food supplementation using the natural source sh oil has been of great interest and its production has increased signi cantly around the world
The studies involving strategies for the extraction and identi cation of arsenolipids have been focusing on arsenic containing long chain fatty acids (As-LCFA), which have been found in different biological matrix like brown alga,[22,23] sh meal,[16] fresh cod liver[20] and oil sh.[10,11,14,21]
Raab et al.[22] describe that among different extractants used for extraction of arsenic compounds in brown alga (Saccharina latissima), the CH2Cl2/methanol (2 : 1 v/v) mixture was the fraction that showed the highest concentration of arsenic (AsFA and arsenic containing hydrocarbons (AsHC)) as well as arsenic containing phospholipids (AsPL)
