“…The work of Fischer et al (1961), was replicated using paper chromatography by Spatz (1967) andSiri ex andMarini (1969). Bufotenine was also found in the urine of schizophrenics given a MAOI alone (Heller, 1966) or in conjunction with betaine , or cysteine (Spaide et al, 1968). However, other workers could not find bufotenine in the urine of schizophrenics (Rodnight, 1956;Sprince et al, 1963;Siegel, 1965;Nishimura and Gjessing, 1965;Kakimoto et al, 1967), or could find it only in medicated and not in unmedicated schizophrenics (Runge et al, 1966).…”
