Abstract

 Flower volatile components of Cinnamomum camphora var. linaloolifera Fujita were extracted by using optimized headspace method and analyzed by using GC-MS technology. The results show that 124 volatile components are identified from C. camphora var. linaloolifera flower, their total relative content is 98.83%. In which, there are 69 terpenes, and their total relative content is 90.11%. Meanwhile, there are a small amount of alcohols, aldehydes, esters, ketones, acids, and aromatics, etc., indicating that terpenes are the dominant flower volatile components of C. camphora var. linaloolifera. Moreover, among terpenes, the relative contents of ocimene, α-muurolene, and caryophyllene are relatively high with values of 14.06%, 12.94%, and 6.01%, respectively, which are the top 3 flower volatile components of C. camphora var. linaloolifera. In addition, (+)-α-longipinene, caryophyllene-(Ⅰ1), syringaldehyde A, and syringaldehyde D are identified in volatile components of C. camphora var. linaloolifera for the first time.
