Estriol
One of the three main natural oestrogens, produced in large amounts by the placenta during pregnancy. It was isolated in 1930 by Guy Marrian and colleagues from the urine of pregnant women; as a medicine it is used to treat menopausal symptoms. This family brings together the active ingredient, pharmacopoeial impurities, metabolites, labelled standards and other impurities.
Did you know?During pregnancy its levels rise about a thousandfold: around 90% of its precursors come from the foetus, and the placenta turns them into oestriol.
