Abstract : During isolation of neurotoxins from the venom of Bungarus multicinctus by means of zone electrophoresis on starch, a non-protein fraction was found in addition to the 4 protein fractions obtained previously. It shows maximum absorbance at 252 millimicrons, positive Molisch's test for sugar and orcinol test for pentose, but negative Loring's test for phosphate. It also shows the same Rf value as guanosine in the paper-chromatogram. Thus, the non-protein substance isolated from the venom is identified as guanosine. Its content in the venom was estimated to be 1.10=0.14%. So far no biological effects could be attributed to the presence of guanosine in the venom. (Author)
