A study on the extent of 18O incorporation into various hydroxy-eicosatetraenoic acids, thromboxane B2 and 2,3-dinor-thromboxane B2 by base-catalysed hydrolysis of their methyl ester derivatives is presented. The amount as well as the position of the inbuilt 18O atoms were determined by gas chromatography/mass spectrometry, utilizing electron impact and positive and negative ion chemical ionization.
本文介绍了一项关于通过其甲酯衍生物的碱催化水解将(^{18}O)掺入各种羟基二十碳四烯酸、血栓素(B_2)和2,3 - 二去甲血栓素(B_2)的程度的研究。通过气相色谱/质谱法，利用电子轰击以及正离子和负离子化学电离来确定内置(^{18}O)原子的数量和位置。
