本文介绍了一种非常灵敏的1-O-烷基-2-乙酰基-SN-甘油磷胆碱(血小板激活因子)的定量方法。1-O-烷基-2-乙酰基-sn-甘油磷胆碱通过磷脂酶-C处理转化为1-O-烷基-2-乙酰甘油,再与五氟苯甲酰氯进行酰化反应。用气相色谱/负离子化学电离质谱法分析了五氟苯二甘油酯。以甲烷为试剂气体,五氟苯甲酰基衍生物主要生成分子阴离子([M]-)。占总离子电流的92%以上。用氚标记的1-O-hexadecyl-2-(2H3)acetyl-sn-glycerophosphocholine作为内标进行定量。标准曲线是线性的,相关系数通常大于0.999。用1pg的氚标记内标物,测量低至100fg的量。
A very sensitive method of 1-O-alkyl-2-acetyl-sn-glycerophosphocholine (platelet activating factor) quantitation is described. 1-O-Alkyl-2-acetyl-sn-glycerophosphocholine is converted to 1-O-alkyl-2-acetylglycerol by treating with phospholipase-C which is in turn acylated with pentaflurobenzoyl chloride. The resulting diglyceryl ester of pentafluorobenzene is analysed by gas chromatography/negative ion chemical ionization mass spectrometry. With methane as the reagent gas the pentafluorobenzoyl acyl derivative yields mainly the molecular anion ([M]-.) representing more than 92% of the total ion current. Deuterium-labeled 1-O-hexadecyl-2-(2H3)acetyl-sn-glycerophosphocholine is used as the internal standard for quantitation. The standard curves are linear and typically have a correlation coefficient of greater than 0.999. Using 1 pg of the deuterium-labeled internal standard, quantities as low as 100 fg are measured.
