Determination of Fatty Acid Composition and Phospholipid Molecular Species of Large Yellow Croaker (Pseudosciaena crocea) Roe from China

The aim of this study is to investigate the composition of the fatty acids and phospholipids derived from large yellow croaker (Pseudosciaena crocea) roe. The composition of the total lipids and the molecular species of phospholipids were determined by gas chromatography-mass spectroscopy (GC-MS) and high performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD), respectively. The results showed that large yellow croaker roe had high levels of the total lipid (19.6% +/- 1.32%, w/w) and phospholipid (61.2% +/- 1.22% of the total lipid). The phospholipid was rich in docosahexaenoic acid (31.0% +/- 0.19% of the total phospholipids), and the major phospholipid molecular species was phosphatidylcholine (PC, 61.06% +/- 0.02% of the total phospholipids, w/w). It was concluded that large yellow croaker roe is expected to be a good resource of phospholipids with a high content of PC.
