Figure 2.
Chromatograms of phospholipids from B. longum species. Most of the phospholipid peaks of the B. longum species remained after treatment with PLA1 (b), indicating that these phospholipids were ether phospholipids (b), and peaks of ether phospholipids disappeared after treatment with DNPH-HCl, indicating that these ether phospholipids were plasmalogens (c). Presence of lysophospholipid (lyso-p-lipid) on the chromatogram after HCl treatment also indicated presence of plasmalogens.?; unidetified lipids.
