<unk>  is a naturally occurring organic compound that is found in anise and fennel. It is a dimeric polymer of anethole. It has estrogenic activity, and along with anethole and photoanethole, may be responsible for the estrogenic effects of anise and fennel.

In fact, it is said that diethylstilbestrol and related drugs were originally modeled after<unk>  and photoanethole.
