The sesquiterpene lactones stizolicin, stizolin, and balsamin were isolated previously by Rybalko from Stizolophus
balsamita (Lam.) Cass. ex. Takht. [1]. We isolated for the first time from this species 9-epibalsamin and 9-epihydroxy-8-
(4′-hydroxysenecioyl)balsamin, which were isolated earlier from Centaurea coronopifolia [2], and isolated for the first time from
a plant species 11,13-dihydrostizolin [3].
