Novel Triterpenoidal Alkaloids from the Roots of Buxus Sempervirens

Natural Product Research, 1998
Abstract Phytochemical studies on the ethanolic extract of the roots of Buxus sempervirens of Turkish origin have yielded two novel triterpenoidal alkaloids, (+)-30-hydroxycyclomicrobuxene (1) and (-)-semperviroxazolidine (2). Their structures were established on the basis of extensive spectroscopic studies.

Steroidal alkaloids from leaves of Buxus sempervirens

Phytochemistry, 1991
Abstract Leaves of Buxus sempervirens of Turkish origin have yielded three new steroidal alkaloids, (+)-sempervirine, (−)-31-acetyl-cyclomicrophylline-A and (−)-benzoylbuxidienine. Two known bases (+)-buxamine-C and (+)-buxabenzamidienine have also been isolated for the first time from this plant. The structures have been determined on the basis of

Alkaloids of Buxus sempervirens var rotundifolia BAILLON

Collection of Czechoslovak Chemical Communications, 1981
Twenty one alkaloids were isolated from the leaves of Buxus sempervirens var rotundifolia BAILLON. Buxaminol-B, cyclobuxine-D, cyclovirobuxine-D, cycloprotobuxine-C, buxamine-E, buxtauine-M and buxpiine-K were those already known. New alkaloids, the constitution and configuration of which were inferred from physical data and corroborated by ...
