Synopsis Using high performance liquid chromatography the presence of natural oestrogen traces in aqueous placenta extracts of human origin has been demonstrated. This study, corroborated by results obtained by colorimetric dosage and by gaseous phase chromatography, reveals the preponderance of oestriol, which represents 80% of all the oestrogens. In all the extracts studied, oestriol concentration was not more than 100° per litre of extract. This quantity of oestrogen contained in human placenta extracts of the Filatov type, even in wide cutaneous applications, cannot influence the subject's hormonal balance.
