A new alkaloid kordiline has been isolated from the epigeal part of Korolkowia sewerzowii. On the basis of the results of a study of the IR, PMR, and mass spectra of kordiline and the products of its transformations, it has been established that kordiline has the structure and partial configuration of 3α,11β-dihydroxy-Δ8-cevanine. © 1985 Plenum Publishing Corporation.
