Populations of bloodroot [Sanguinaria canadensis L. (Papaveraceae)] are found throughout the easternforests of North America, with particular abundance in the southern Appalachian Mountains.Increasingly, it is finding use in Europe as a nonantibiotic animal feed supplement to promote weightgain. As efforts to cultivate this herb are underway, there is a need to understand the effect ofagronomic permutations on both the dry mass rhizome yield and the yield of benzophenanthridinealkaloids. Month-to-month variability of the concentration of the alkaloids sanguinarine and chelerythrine in both cultivated and wildcrafted bloodroot was examined. The alkaloid yield was consistentlyhigher, but more variable, in wildcrafted plants. On average, cultivated rhizomes were both largerand more consistently sized than those that were wildcrafted. The concentration of a suite of traceelements was measured in soil that was collected concomitantly with each plant accession. Differencesin element profiles were compared against alkaloid yields.
