Lipidomics and Anti-Inflammation Activity of Brown Algae, Lobophora sp., in Vietnam

Table 3

Molecular species of phospholipid including PI, PC, PG, and PA groups identified by HPLC-HRMS as negative [M − H] ion and positive [M + H]+ ion, and identification as phospholipid and fatty acyl composition confirmed by the analysis of the LC-MS/MS spectra of each ion.
