METHOD FOR OBTAINING OESTROGEN FROM MARE URINE.

摘要

The invention relates to a method for obtaining extracts of a natural mixture of conjugated oestrogen from the urine of pregnant mares (PMU). The extracts obtained according to the inventive method fulfil the pharmaceutical specification relating to conjugated oestrogen and the reduction of the free oestrogen content, even when PMU is used which is old, and/or stored or transported at a high temperature. PMU extracts containing a mixture of conjugated oestrogen are obtained by means of solid phase extraction on semipolar adsorption resins.
