Numerous cases of livestock poisoning due to the common cocklebur have been recorded in the literature during the past three decades. From the stock raiser’s standpoint the question of the poisonous properties of this plant has become very important for it grows worldwide and is reported to cause heavy losses annually. Published statements concerning the toxicity of this prolific weed and the nature of the toxic principle , if one exists, are quite contradictory and controversial. The references which state that there is a toxic principal have designated it as a glucose, an alkaloid, a saponin, and a hydrocarbon. There are many reports in the literature that the plant is innocuous. Consideration of the economic importance of the cocklebur to the stock raiser and the controversy that exists concerning its toxicity has prompted this study to attempt isolation of a toxic principle from the bur and seed.
