title: Does Donglan lacquer tree belong to Rhus vernicifera species?
abstract: The lacquer trees in Donglan of Guangxi Province, China, were identified totally as the species Rhus succedanea found in Vietnam and Taiwan region, based on the results of pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), an easy and effective method to identify species of trees among those with similar properties. Analyses by IR and NMR, the drying properties, and conventional morphology also confirmed that the Donglan lacquer trees do not belong to Rhus vernicifera, like most trees of the China mainland. Some differences, however, such as the enzymatic activity and the components of the lacquer, were found between the Donglan lacquer and the Vietnam lacquer. The Donglan lacquer has a shorter drying time than the latter.
