It is the chief constituent of the poisonous American wormseed oil and is found in amounts of up to 40% in oE of Cheno podium amhrosioides, although not found in other oils of the same type [52]. Ascaridole, as an inner peroxide, is found on chromatograms at a higher position than the hydroperoxides which have been repeatedly detected as intermediates during epoxide formation. Using n-hexane-diethyl ether (87 + 13), the three limonene peroxides can also be separated under standard conditions (hRf 22, 27 and 33) [85]. 

Ascaridol contains a 1,4-peroxide bridge. It is the main constituent of the volatile oil of American wormseed (Chenopodium ambrosioides var. anthelminticum, Chenopodiaceae). It has anthelmintic properties but is also toxic to mammals. Ascaridol can also be found in chemotypes of some Achillea species. 

This oil, known as American wormseed oil, is distilled from the herb Ghmopodiwm ambrosioides, var. anthehnmticum, in the United States, principally in Maryland. A certain amount of oil is distilled from the fruit only. Normal oils have the following characters —...
