[Excretion of estriol-3-sulfate in the urine of pregnant women during the last trimester of pregnancy].
In this publication a method is given for quantitative determination of estriol-3-sulfate in urine of pregnant women. After separation of estriol-3-sulfate from glucuronides by liquid partition using acetone and NaOH the sulfate is hydrolyzed to estriol. The estriol is converted to an azodye which is separated by TLC and measured by remission analysis which a chromatogramm spectrophotometer. 59 cases have been investigated and the excretion pattern is given for estriol-3-sulfate in the 3rd trimester of pregnancy. The average excretion is 100 mug/24 hours in the 28th week and 356 mug/24 hours in the 42nd week of pregnancy.
