摘要
The use of (3,3,4,4-2H4)PGE2 as internal standard for the quantitative measurement of PGE1 by gas chromatography-mass spectrometry was reported. A method for the simultaneous analysis of PGE1 and PGE2 was also described. The PG were analyzed by selected ion monitoring as the methyl ester-trimethylsilyl ether (ME-TMS) derivatives of PGB1 and PGB2, respectively. A linear response over the range 1-70 ng (2.8-198 pmoles) was demonstrated in all cases. The use of this procedure is exemplified by its application to the PG analysis of sheep seminal vesicles.
