Abstract: The headspace solid phase microextraction(HS–SPME)combained with the GC–MS test were used to detect the volatile components of six Calycanthaceae plants. Moreover,in order to investigate the volatile components difference of the tender shoots between several species(strains)of Calycanthaceae,the common component analysis,principal component analysis and cluster analysis of the volatile components were adopted to compare the Chimonanthus nitens(a widely used medicinal plant)with other tested species(strains). The results showed that a total of 141 volatile components were detected in the tender shoots, with 47 in Ch. praecox‘Hongyun’,48 in Ch. praecox‘Jinyu’,44 in Ch. praecox‘Yanlingsuxin’,44 in Ch. nitens,48 in Calycanthus chinensis and 46 in Ca. floridus. Alkenes and alcohols were the main volatile components in the six plants. Moreover,when compared with Ch. nitens,the common volatile components of Ch. praecox‘Hongyun’,‘Jinyu’,‘Yanlingsuxin’,Ca. chinensis,and Ca. floridus were 15,18,10,14 and 20,respectively. PCA analysis and cluster analysis showed that Ca. chinensis falled into a group,while Ch. nitens and Ch. floridus belong to one group,and Ch. praecox‘Hongyun’,‘Jinyu’and‘Yanlingsuxin’are the other one. Furthermore,we found eudesmol and β-terpinene were the primary differential volatile compounds when executing the comparative analysis with Ch. nitens. Overall,abundant volatile components were found in tender shoots of the six Calycanthaceae plants,and our study have great potential for medical development though there are certain discrepancy among different species(strains)
