Falcarindiol is a polyyne found in carrot roots which has antifungal activity.[1][2] Falcarindiol is the main compound responsible for bitterness in carrots.[3] Falcarindiol and other falcarindiol-type polyacetylenes are also found in many other plants of the family Apiaceae, including some commonly used seasonings such as dill and parsley.[4] A variety of bioactivities have been reported so far for falcaridiol and the falcarindiol-type polyacetylenes,[5][6][7] and because of potential health-promoting metabolic effects these compounds are studied as potential nutraceuticals.[8] It is the most-active among several polyynes with potential anticancer activity found in Devil's Club (Oplopanax horridus), a medicinal plant used by many indigenous peoples in Alaska and the Pacific Northwest.[9]
