Apterin is a furanocoumarin. It is the glucoside of vaginol. It has been isolated from the root of plants in the family Apiaceae such as members of the genus Angelica, including the garden angelica[1] and in Zizia aptera.[2]

It is reported to dilate coronary arteries as well as block calcium channels.[citation needed]
