Summary
A sesquiterpene lactone with the composition C20H24O5, mp 104°–105° C, [α]D −212.4° C (alcohol) has been isolated from the roots ofFerula oopoda Boiss. and has been called badkhysinin. Badkhysinin is an ester of angelic acid and an epoxyhydroxylactone C15H18O4 with mp 185°–186° C apparently related to guaianolide with a hydrocarbon skeleton of irregular structure. A number of possible structural formulas for badkhysinin are given.
