Abstract

Solid phase micro extraction ( SPME) has been widely used for volatile extraction of gas, liquid and solid matrices. Four fibers, i. e. 100'mPDMS, 85'mPA, 65'mPDMS/DVB and 50 /30'mDVB /CAR /PDMS,were selected for extraction in camellia oil volatile analysis. Results show that: (1) Benzaldehyde, octanal, octonol,nonanal, and nonanol which have relatively high boiling points are sensitive in 65'm PDMS/DVB fiber, while the relatively low boiling point compounds are sensitive in 50 /30'm DVB /CAR /PDMS fiber; (2) The rank sequence oftotal peak areas in gas chromatography isDVB /CAR /PDMS > PDMS/DVB > PA > PDMS; (3) L inear regressive rela2tionship between the total peak area and volatile amount (0'120'g/g) in DVB /CAR /PDMS, PDMS/DVB, PA,PDMS exists with R2 of 0. 9939, 0. 9888, 0. 9176 and 0. 9917, respectively. These factors indicate that 65 'mPDMS/DVB and 50 /30'm DVB /CAR /PDMS are suitable for the extraction of volatile of camellia oil.
