The research aims to study phospholipids (PL) classes and molecular species of large yellow croaker (Pseudosciaena crocea) roe. Both gas chromatographymass spectroscopy (GC-MS) and high-performance liquid chromatography with evaporative light-scattering detection (HPLC-ELSD) were utilized to analyze and identify the PLs fatty acids compositions and classes in the P. crocea roe, respectively. Docosahexaenoic acid (DHA, C22:6) and eicosapentaenoic acid (EPA, C20:5) account for 35.0% and 6.9% of the PLs. Phosphatidylcholines (PC), lysophosphatidylcholines (LPC), phosphatidylethanolamines (PE) and phosphatidylinositols (PI) account for 76.36 ± 0.62%, 12.30 ± 0.55%, 9.12 ± 0.02% and 1.09 ± 0.01% of the total PLs, respectively. In addition, the PLs molecular species were characterized by ultra-high performance liquid chromatography-electrospray ionization-quadruple-time of flight-mass spectrometry (UPLC-Q-TOF-MS). A total of 92 PLs molecular species was identified, including 49 PCs, 13 PEs, 10 phosphatidic acids (PAs), 13 phosphatidylserines (PSs), 3 phosphatidylglycerols (PGs), 2 sphingomyelins (SMs), and 2 PIs of the P. crocea roe.
本研究旨在研究大黄鱼（Pseudosciaena crocea）鱼卵中的磷脂（PL）种类和分子种类。分别采用气相色谱-质谱联用（GC-MS）和高效液相色谱-蒸发光散射检测（HPLC-ELSD）分析鉴定鱼卵中 PL 的脂肪酸组成和种类。二十二碳六烯酸（DHA，C22:6）和二十碳五烯酸（EPA，C20:5）占 PL 的 35.0%和 6.9%。磷脂酰胆碱（PC）、溶血磷脂酰胆碱（LPC）、磷脂酰乙醇胺（PE）和磷脂酰肌醇（PI）分别占总 PL 的 76.36±0.62%、12.30±0.55%、9.12±0.02%和 1.09±0.01%。此外，还通过超高效液相色谱-电喷雾电离-四极杆飞行时间质谱（UPLC-Q-TOF-MS）对 PL 的分子种类进行了表征。共鉴定出 92 种 PL 分子种类，包括 49 种 PC、13 种 PE、10 种磷脂酸（PA）、13 种磷脂酰丝氨酸（PS）、3 种磷脂甘油（PG）、2 种鞘磷脂（SM）和 2 种 PI。
