Lotaustralin is a cyanogenic glucoside found in small amounts in cassava (Manihot esculenta), lima bean (Phaseolus lunatus),[1] roseroot (Rhodiola rosea)[2] and white clover (Trifolium repens),[3] among other plants. Lotaustralin is structurally related to linamarin, another glucoside found in these plants, and differs from it only by the presence of an extra methyl group. Both lotaustralin and linamarin may be hydrolysed by the enzyme linamarase to form glucose and a precursor to the toxic compound hydrogen cyanide.
