Abstract
The aroma constituents of Anjibaicha were extracted by fully automated headspace solid phase microextraction(HS-SPME),and were identified by GC-MS,and the relative contents of various aroma constituents were determind by area normalization.Results showed that 73 aroma constituents were identified and accounted for 95.59%of total aroma constituents,and the main kinds of aroma constituents in Anjibaicha were esters(30.17%),alcohols(27.75%),ketones(13.75%) and hydrocarbon compounds(9. 24%),respectively.The major aroma compounds of Anjibaicha are hexadecanoic acid methyl ester,geraniol,hexadecanoic acid,9,12,15-octadecatrienoic acid methyl ester,phytol, phytone, dihydroactinidiolide,(Z, Z)-9, 12-octadecadienoic acid methyl ester, betaionone,cedrol,jasmone,nerolidol,linalool,caffeine and geranyl acetone.
