Distribution of<I> S</I>-alk(en)yl-l-cysteine Sulfoxides in Garlic <I>(Allium sativum</I> L.)
Horníčková, J. | Velíšek, J. | Ovesná, J. | Stavělíková, H.
This study was devoted to distribution of <I>S</I>-alk(en)yl-L-cysteine sulfoxides (particularly alliin, methiin, and isoalliin) in plants of <I>Allium sativum</I> L. and to diversity of selected groups of garlic clones representing the three basic garlic morfotypes (i.e. flowering plants, scape absent and semi-bolters – this classification is based on IPGRI descriptors). The content of <I>S</I>-alk(en)yl-L-cysteine sulfoxides, important non-volatile precursors flavour-active compounds, was determined in four parts (roots, bulbs, false stems, and leaves) of six different clones of garlic (<I>Allium sativum</I> L.) plants collected during the whole of vegetation – in March, April, May, June, and July. The contents of target <I>S</I>-alk(en)yl-L-cysteine sulfoxides were dependent not only on part of garlic plants but also on morfotype of garlic plants and vegetation period.
