[Group separation of ethylene oxide 1,2-14c fumigated coca-powder derivatives and their distribution of radioactivity (author's transl)].
A procedure based on extraction, column chromatography and precipitation is described for the separation of ethylene oxide-1,2-14C fumigated coca-powder derivatives in 9 different groups. As it was found in wheat [1], the major portion of radioactivity lies in water extract; in coca-powder the major portion of radioactivity is also found in low molecular components.
