Subjects: Chemistry, Q, QD1-999, Telekia speciosa, корни, сесквитерпеновые лактоны, эвдесманолид, спектроскопия, ИК, 1Н-, 13С-, 13С Dept 135 ЯМР-спектры, Science, Telekia spesiosa, roots, sesquiterpene lactones, IR-, 13C NMR, 13C Dept 135 spectroscopy

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.
