Abstract

ABSTRACT: Thitsiol separated from Gluta usitata lacquer sap was polymerized by thermal catalysis, and the dimers were purified by HPLC. The dimer chemical structures were characterized by NMR and field desorption mass spectrometry spectroscopy. Almost all dimers have biphenyl nuclear–nuclear (C–C) structure that is somewhat different to the thitsiol dimer obtained from laccase catalysis. Based on these results, the thermal polymerization mechanism of thitsiol was discussed.
