The structures of thitsiol dimers from Melanorrhoea usitata were characterized by means of high-resolution NMR spectroscopy involving two-dimensional NMR measurements such as field gradient DQF-COSY, HMQC, and HMBC experiments. Almost all proton and

3-(10-Phenyldecyl)catechol was synthesized by the reaction of catechol and 1-phenyl-10-iododecane, followed by de-protection of the hydroxyl groups of catechol; it was then polymerized into synthetic lacquer film by laccase enzyme, and characterized
Two oriental lacquers from Rhus succedanea and Melanorrhoea usitata were characterised by Py-GC–MS with in situ silylation using HMDS. Pyrolytic markers, which were helpful in differentiating between the lacquers, were identified in their silylated

Three lacquer saps (Rhus vernicifera, Rhus succedanea and Melanorrhoea usitata lacquer saps) are used for a surface coating in Asia. We previously reported the identification of urushiol components in Rhus vernicifera lacquer sap (Japan, China and Ko
