摘要：Volatile components of Callistemon rigidus were analyzed by headspace solid phase microextraction-gas chromatography/mass spectrometry.The results showed that 34 volatile components,including alkenes,esters,alcohols,and a small amount of acids,heterocycles and alkanes,were identified from C.rigidus flowers.The main components were eucalyptol,aspidinol,terpilenol,vanillylacetone,α-phellandrene,4-pyran-4-1,2,3-dihydro-3,5-dihydroxy-6-methyl,pinene,3-methylcatechol,naphthalene,(+)-limonene,7-methylxanthine and (+)-aromadendrene,the contents of which were 35.39%,10.09%,8.86%,4.51%,3.25%,2.81%,2.75%,2.43%,2.29%,1.3%,1.12% and 1.07%,respectively,all of which accounted for 75.69% of the total relative content.Monoterpenoids are the main components of various types of essential oils.This study provides a theoretical basis for the deep processing of this variety.
