 note = {The chemithermomechanical pulp (CTMP) papers prepared from different Eucalyptus globulus trees individuals, which showed various degree of yellowing after UV irradiation, was characterized by focusing on compounds repressing paper recyclability using pyrolysis-gas chromatography (Py-GC) in the presence of organic alkali; tetrabutylammonium hydroxide (TBAH). Two different origin of CTMP papers prepared from different individuals of Eucalyptus globulus trees showing high and low yellowing after photo-irradiation was compared before UV irradiation. As a result, Many polyphenol fragments derived from both liginin and extractives were observed as 30 peaks on the pyrogram. Among these peaks, Syringol 1+6, methylsyringol 3+11, methylguaiacol 4 and vinylsyringol 7+14 were recognized as major fragments relating to photo-yellowing level in over 5 pts difference of relative molar yields between two samples. G-lignin\nfragment seems to enhance photo-yellowing although S-lignin fragment works vice versa. They can be used as indices for prediction of photo-yellowing level.},
