Open publisher page 1 citations

Abstract

A method for the determination of volatiles from garlic oil using headspace solid phase microextraction(HS-SPME)and gas chromatography-mass spectrometry(GC/MS)was presented.By total peak area and ratio of total peak area to number of peaks used as the main evaluating indexes,the analysis parameters of different SPME fibers,extraction time,extraction temperature,desorption time were optimized.The optimum extraction conditions were obtained as follows:85μm PA fiber,exposure for 35min at 40℃,and desorption for 3min at 250℃. The results showed that SPME was effective to analysis of the volatiles in garlic oil,twenty-seven compounds were identified.The method is simple,quick,solventless and inexpensive.
