 Title    Mass Spectroscopic Fragmentation Reactions, XXI [1] Factors Influencing the Loss of Xylene and Toluene from the Polyene Chain of Carotenoids  
 Abstract    By examining suitably substituted analogs of carotenoids the steric and electronic influences governing the elimination of xylene and toluene from the polyene chain have been clarified.

 Title    Chemilumineszenz der S02-Oxidation Chemiluminescence of SO2-Oxidation  
 Abstract    The reactions of diluted aqueous solutions of SO2 resp. HSO3-ions with MJ1O4-or Ce 4+ ions in the pH range 1-4 produce chemiluminescence in the spectral region of 450-600 nm. Measurements of the time course of the light emission and their simulation on an analog computer led to a reaction scheme in which a recombination product of primarily formed HSO3 radicals -of a lifetime of about 1 second -appears as precursor of electronically excited SO2 molecules. The participation of singlet oxygen can be excluded because at least the reaction with Ce 4+ ions proceeds also in the absence of oxygen.

 Title    Achatina fulica  
 Abstract    Three different polyvalent proteinase-inhibitors have been detected in the albumin gland o f the snail, Achatina fulica and identified by means of fibrin-agar immunelec­ trophoresis. The inhibitory activity o f these substances against several proteinases from different sources was investigated.
