A method for the simultaneous quantitation of 7 estrogens in pregnancy urine is described. It involves enzymatic hydrolysis extraction of free steroids, ion-exchange column chromatography and quantitation of the trimethylsilyl derivatives by gas chromatography on OV 1. Data obtained from normal and twin pregnancies and from women with anencephalic fetus or intra uterine fetal death are analysed. The sensibility of the method is about 40 mug of each estrogen by liter of urine.
本文描述了一种同时定量测定孕妇尿液中7种雌激素的方法。该方法包括游离类固醇的酶水解提取、离子交换柱色谱法以及通过气相色谱法在OV 1上对三甲基硅烷基衍生物进行定量。分析了从正常妊娠和双胎妊娠以及无脑儿或宫内胎儿死亡的妇女中获得的数据。该方法的灵敏度约为每升尿液中每种雌激素40微克。
