Abstract

Six bases have been isolated from the leaves of the plantZiziphus jujuba Mill. family Rhamnaceae, cultivated in Tashkent: coclaurine, which has been isolated previously, and isoboldine, norisoboldine, asimilobine, which have been isolated for the first time, and the new juziphine and juzirine. It has been established that juziphine has the structure of 8-hydroxy-1R-(4′-hydroxybenzyl)-7-methoxytetrahydroisoquinoline, and juzirine that of 7-hydroxy-1-(4′-hydroxybenzyl)-6-methoxyisoquinoline. Juziphine has also been isolated from the epigeal part ofCorydalis gortschakovii.
