| Abstract: | The volatile compositions from the Rhodiola kirilowii were obtained by headspace solid phase microextraction-gas chromatography spectrometry-mass spectrometry(HS-SPME-GC/MS).The effects of different fibers on detecting result were discussed.The results showed the volatile compositions from Rhodiola kirilowii could be effectively extracted by the fiber of DVB/CAR/PDMS.These volatile compounds were mainly including some alcohols,such as cis-geraniol(14.38%),1-octanol(10.99%),cis-linalool oxide(8.10%),trans-linalool oxide(3.44%),3-penten-2-ol(3.08%),4,8-dimethyl-1,7-nonadien-4-ol(2.96%),phenylethyl alcohol(2.7%),1-decanol(2.42%),esters as nerol acetate(3.84%),and some alkanes as 3,7-dimethyldecane(3.52%) and heneicosane(3.2%). |
