Steroid extraction process from urine sources

摘要

A process in which urine is optionally filtered to remove solid extraneous matter and optionally treated so as to reduce the phenolic content of the urine to give and the resulting fluid is then subjected to a solid extraction of the major concentration steroids content therefrom by a first suitable resin (to yield a first resin laden with major concentration steroids and a minor concentration steroid laden first liquid remainder). The minor concentration steroid liquid remainder is subjected to a solid extraction of the minor concentration steroid content therefrom by a second suitable resin (to yield a second resin laden with minor concentration steroids and a second liquid remainder). The first and second resins laden with their respective steroids are then eluted and the eluates are collected separately and optionally subjected to further purification and chromatographic separations, with each resulting separate collection being analyzed for the steroid content thereof. The separate analyzed materials are dried and stored for recombination in an appropriate manner to meet a desired profile. The ultimate product has very nearly the same steroid components and concentrations from batch to batch.
