Simultaneous Determination of Diallyl Trisulfide,Diallyl Disulfide and Re-lated Substances in Allicin by Gas Chromatography
OBJECTIVE A gas chromatographic method for simultaneous determination of allicin index compo-nents and related substances was established.METHODS Diallyl trisulfide and diallyl disulfide were used as standard solutions,acetophenone as internal standard,n-hexane as solvent,samples were prepared,detected by FID detector,and quantified by internal standard method.RESULTS The average recovery of diallyl trisulfide was 98.71%,RSD =0.86%;The average recovery of diallyl disulfide was 97.28%,RSD =1.33%.CONCLUSION This method is simple,fast and accurate,and can be used for the determination of allicin content and the limit control of related substances.
