反応手順

Allicin is produced from the Alliin, prepared by the method detailed in (d), by the simple procedure of either dissolving in distilled water or taking a given amount of the liquid Alliin produced above and adding a small amount of fresh garlic in the form a pealed complete whole clove. The mixture is then combined in a blender for up to 5 minutes, typically 2 minutes, resulting in the complete disintegration of the garlic clove and the release of the garlic enzyme Alliinase. Conversion of the Alliin present by the enzyme alliinase occurs rapidly with approximately 50% of the Alliin being converted. Further additions of garlic result in a further conversion of Alliin to Allicin. The HPLC method described by Iberl, Müller and Knobloch (1990) using a derivatising agent showed that both isomers of Alliin were converted to Allicin and substantially all Alliin present could be converted to Allicin. While the activity of the enzyme rapidly decreased following addition some activity remained for up to 24 hours, as demonstrated by FIG. 1, with the Allicin increasing and the Alliin decreasing with time without further addition of the enzyme. Storage of the reaction mixture at 20° C. did not completely stop the reaction.
