Abstract:
1. A method for obtaining steroids from urine, said urine containing phenolic constituents, a first group of esterified steroid constituents (first ESC) and a second group of esterified steroid constituents (second ESC), said method comprising: a. contacting urine, optionally pretreated by: with a second non-ionic resin (second resin), said second resin capable of extracting at least one constituent of said first ESC without substantially extracting said second ESC, to result in a first ESC constituent laden second resin and a liquid remainder, and separating said first ESC constituent laden second resin from said liquid remainder; b. contacting said liquid remainder with a third cationic resin (third resin), said third resin capable of extracting at least one constituent of said second ESC from said liquid remainder to result in a second ESC constituent laden third resin and a second liquid remainder and separating said second ESC constituent laden third resin from said second liquid remainder; and c. independently recovering the first ESC from said first ESC laden second resin and the second ESC from said second ESC laden third resin.
