title: [Isolation of the Derivatives from Coca-Powder Fumigated by Ethylene Oxide 1,2-14 C and their Structure Suggested on the Basis of I. R. and Mass-Spectrometry].
abstract: In Coca-powder fumigated with Ethylene Oxide-1,2(14)C, several derivatives were isolated by extraction and preparative Thin Layer Chromatography. Of the two compounds isolated from the water-extract, the structures have been suggested as N,N-Bis-(Di-Ethoxy-O-Hydroxy-ethyl)-Isoleucyl-Alanyl-Cysteine (MW = 569)and N-Ethoxy-O-Hydroxyethyl)-Tyrosine (MW = 269), based on I.R. and Mass Spectrometry. Their approximate concentrations were found to be 20 and 50 mg/kg respectively.
