| Abstract: | Nature garlic oil and synthetical allicin were analyzed by gas chromatorgpahy-mass spectrometry, and the main components and their relative contents were obtained. Compared mass chromatograms of nature garlic oil with that of synthetical allicin, relative content of 0.24% of allyl chloride was found in synthetical allicin, but not in nature garlic oil. The presence of alllyl chloride in synthetical allicin was deduced resulting from the material residue in the synthesis process. According to the presence or absence of allyl chloride, the rapid, accurate method could be used to judge whether the synthetical allicin was added to garlic oil samples or not. |
