✦ Synopsis


890 ml of urine of rats treated with ['4C]205-734 was desalted over an Amberlite XAD-2 adsorption column. The methanol extract dissolved in 10 ml methanol was injected onto an anion exchangecolumn (Nucleosil 10 SB 250 X 1 Omm i.d.) equilibrated in methanol. A gradient of decreasing methanol proportion ver- sus a 0.2 u ammonium hydrogen carbonate buffer eluted a pure glucuronide of 205-734. Its structure was established by NMR, MS, UV, and IRanalyses. This procedure is simple, rapid, andvery selective for the compound of interest.
