Abstract: The volatile oil from Vaccinium bracteatum Thumb. leaves was analyzed by GC-MS. 65 peaks were separated and 49 compounds were identified, which represented about 91.94% of the total content. The main chemical constituents were terpenes 54.75%, open chain alkanes 6.93%, cycloparaffins 20.13%, olefins 0.60%, aromatics 1.60%, phenol, ether and alcohol 3.39%, aldehyde and ketone 2.14%, ester 1.15%, heterocyclic compounds 0.47% and amines 0.78%. Nerolidol 20.01%, (Z,Z,Z)-1,5,9,9-tetramethyl-1,4,7-cycloundecatriene 17.99% and caryophyllene 9.59% were the main components in the identified terpenes. 12 kinds of industrial production flavors were found from volatile oil in Vaccinium bracteatum leaves, and five components have insecticide and antibacterial activity.
