Falcarindiol

Falcarindiol is a polyyne found in carrot roots which has antifungal activity. Falcarindiol is the main compound responsible for bitterness in carrots. 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.

A variety of bioactivities have been reported for falcaridiol and the falcarindiol-type polyacetylenes,  and because of potential health-promoting metabolic effects these compounds are studied as potential nutraceuticals. Falcarindiol is the most-active among several polyynes found in Devil's club (Oplopanax horridus) that inhibit cell proliferation.
