Besides izoalantolactone two new components (I, C15H22O2, m.p. 173–174 °C; II, C12H14O4, oily compound) have been isolated from roots of Telekia speciosa (Schreb.) Baumg. by column chromatography. On the basis of chemical and spectral data (IR-, 1H, 13C NMR, 13C Dept 135) it was ascertained that compound I have structure identific with 11,13-dihydroisoalantolactone, II - diethyl ester ftalic acid. The 11,13-dihydroisoalantolactone and diethyl ester ftalic acid from Telekia soeciosa have been isolated first.
