采用高效液相色谱—飞行时间质谱法对比分析棕榈油、猪脂、牛脂和羊脂甘油三酯，结果显示4种油脂的甘油三酯种类和含量均不相同。从棕榈油、猪脂、牛脂和羊脂分别鉴定出16、19、15、13种甘油三酯，三饱和脂肪酸甘油酯分别占9．13％、1．46％、13．75％及9．05％。棕榈油中 PPO 含量最高，占34．41％，其次是 PLO ＋SLL、PPL 和 PPP。猪脂中含量较高的甘油三酯分别为 OLS、PLO＋SLL、POS 及 POO，占总甘油三酯的67．65％；牛脂中含量较大的甘油三酯为 POS 和 OLS，占40．17％，其次为 PPO、SSL 及 SOS；羊脂中含量较大的甘油三酯为 SSL、POO、SOS 和 POS，占73．12％。同时，采用主成分分析法对4种油脂进行了统计分析。

Triglycerides in palm oil and animal fats such as lard,beef tallow and suet were investigated by HPLC /Q -TOF.The results showed that the composition and content of triglycerides in each oil or fat were different.16,19,15 and 13 triglycerides were identified in palm oil,lard,beef tallow and suet,respec-tively;in which the content of trisaturated glycerides were 9.13%,1.46%,13.75% and 9.05%,sepa-rately.PPO was the major triglyceride (34.41%)in palm oil,followed by PLO +SLL,PPL and PPP. OLS,PLO +SLL,POS and POO with content of 67.65% were the dominant triglycerides in lard.In beef tallow,the content of POS and OLS was 40.17%,the content of PPO、SSL and SOS was relatively high. SSL、POO、SOS and POS in suet was 73.12%.Meanwhile,4 oils and fats were statistically analyzed u-sing principal component analysis (PCA).
