CORESTA Meeting, Smoke Science/Product Technology, Freiburg, 2003, STPOST 02 Removal of free radicals in mainstream cigarette smoke by filters including antioxidant rosemary extract: quantification by a new and robust LC-MS/MS method EMAMI I.; MASSELOT D.; VANDOOLAEGHE P.; LE GAC S.; ROLANDO C. Biosynthec, Paris, France The presence of free radicals in cigarette smoke was demonstrated more than 40 years ago by freezing of mainstream smoke and analyzing the resulting solid using ESR techniques. 1 Free radicals play a central role in ageing diseases like cancer,...
CORESTA Congress, New Orleans, 2002, STPOST 13 A new and efficient method for detecting free radicals by LC-MS/MS. Application to the optimization of a cigarette filter which remove free radicals in cigarette smoke MASSELOT D.; EMAMI I.; ROLANDO C.; LE GAC S. Biosynthec, Paris, France Free radicals are involved in a wide variety of ageing diseases such as cancer, cardiovascular diseases and arteriosclerosis: these are known effects that have driven us to want to radically decrease the free radical contents in cigarette smoke....
