摘　　要：This paper deals with the discolorations of the canes of three rattan species, i.e., Calamus simplicifolius , Calamus tetradactylus , Daemonorups margaritae and its cause. The apparatus, X25F Xenon Fade Meter and CR-300 Chromatic Aberration Meter and the extractions, hot water and alcohol-benzene were applied for the test. The preliminary results indicated that the discoloration of D. margaritae was severer than the other. This is related with extract of the rattan cane because quantity of photoinduced discoloration (Δ E *ab ) was significantly decreased after extracting and the quantity of the extract of D. margaritae was largest than the other. There was similar effect between the hot water and alcohol-benzene extracting on the discoloration.This paper deals with the discolorations of the canes of three rattan species, i.e., Calamus simplicifolius, Calamus tetradactylus, Daemonorups margaritae and its cause.
