Patent ID: 7235262

Claim:
A process of preparing a white powder from cow urine distillate (GM-IV), said process comprising: a) mixing a volume of cow urine distillate with a volume of methanol, the volume of the methanol being half the volume of the cow urine distillate; b) extracting with hexane to produce a hexane fraction (GM-I) and an aqueous fraction; c) extracting the aqueous fraction with ethyl acetate to produce an ethyl acetate fraction (GM-II) and an aqueous fraction containing a white precipitate; d) extracting the aqueous fraction containing the white precipitate with butanol to produce a butanol fraction containing a pale yellow precipitate (GM-III) and an aqueous fraction with a white precipitate; and e) drying the aqueous fraction containing the white precipitate from step d) to form the white powder from cow urine distillate (GM-IV).
