Three lacquer saps (<I>Rhus vernicifera, Rhus succedanea</I> and <I>Melanorrhoea usitata</I> lacquer saps) are used for a surface coating in Asia. We previously reported the identification of urushiol components in <I>Rhus vernicifera</I> lacquer sap (Japan, China and Korea). In this study, laccol components in <I>Rhus succedanea</I> lacquer sap (Vietnam and Taiwan) were synthesized by Wittig reaction of ylides derived from alkyl- and alkenylphosphonium iodides with aromatic parts such as 3-(10-oxo-1-decyl)catechol diacetate and 3-(10-oxo-1-decyl)phenol acetate, followed by removal of acetate groups. Identification of natural laccol components from <I>Rhus succedanea</I> lacquer saps was carried out by GC and GC/MS and comparison with synthesized laccol components. Stereostructures and constituent of all laccol components in <I>Rhus succedanea</I> lacquer sap were clarified. By quantitative analysis using GC, the most abundant component was 3-[(10<I>Z</I>, 13<I>E</I>, 15<I>E</I>)-10, 13, 15-heptadecatrienyl]catechol except for red lacquer sap, but the abundance of trienyl components was not higher than that in the Japanese lacquer sap such as <I>Rhus vernicifera</I>. The amount of monoenyl components were higher than in Japanese lacquer sap.<br>
