Previous work Bohlmann and King (1991) reported the isolation of the guaianolide eremanthin, furoheliangolide 8-epi-budlein A, triterpene lupeol and its acetate from aerial parts and b-amirin, eremanthin, dehydro-costus-lactone, tridecapentaynene and tetra- deca-8,10,12-triyne-4E,6E-dien-1-ol from roots of Episcothamnus candelabrum (Schultz-Bip.)
