Abstract: The aim of this experiment was to analyze the variation of component and relative amount of volatile compounds from tea plant infested by Exobasidium vexans Masseeon (E. vexans). The volatile compounds released from tea plant (Camellia sinensis var. assamica) healthy and diseased were analyzed by SDE/GC/MS. Result showed that a total of 37 volatile compounds were detected from the healthy tea plant, as 80.195% of total compounds identified from the healthy tea plants. A total of 56 volatile compounds, 92.166% of compounds were identified from the infected plants. However, 13 volatile components which was existed in intact tea leaf were not detected and 31 new volatile compounds were in E. vexans infested plants. Linalool was the main volatile compound in intacted Camellia sinensis var. assamica. The kinds of azotic, sulfur, terpenes, aromatic, green leaf volatile were main volatile compounds in tea plants infested by E. vexans.

Key words: Exobasidium vexans massee, infested, volatile compounds, GC/MS
