The present invention relates to improvements in or relating to Allium extracts. In particular, it relates to improvements in or relating to extending the therapeutic half- life or duration of Allium extracts. The invention also relates to the synthesis of certain thiosulfinate compounds, especially to the synthesis of methyl allyl thiosulfinate and allyl methyl thiosulfinate, in particular from either methiin or alliin alone or a mixture of both. The invention further relates to the synthesis of methyl allyl thiosulfinate, allyl methyl thiosulfinate, allicin, and methyl methyl thiosulfinate in a mixture with varying molar or mass ratios depending on the reaction conditions, in particular from either methiin or alliin alone or a mixture of both. A high yielding, optimized synthesis of allicin starts from alliin, whereas methyl methyl thiosulfinate is advantageously obtained from methiin. Also provided is a kit comprising methiin in a first container and/or alliin in a second container and an allinase source, in particular garlic powder in a third container. Finally, the invention provides a method of preparing a mixture of methyl allyl thiosulfinate, allyl methyl thiosulfinate, allyl allyl thiosulfinate (allicin) and methyl methyl thiosulfinate from methiin and pieces of an Allium species. |
