Aspidosperma australe

In addition to olivacine and guatambuine (Section VII, C), an unnamed alkaloid, mp 186°-188°, resembling uleine in its color reactions, has been isolated from Aspidosperma australe (147)3. A glycosidic alkaloid, quebrachacidine, C26H28N2O11, has been found in A. quebracho-bianco (195), and its aglycone has been prepared. Several alkaloids have been reported in A. oblongum and A. album (196), notably kromantine, mp 176°, [a]D+ 159° (in chloroform), from the latter species (196a). [Pg.505]

Research on the biosynthesis of uleine (114) and apparicine (115) has been reviewed. The review includes unpublished results of preliminary studies in Aspidosperma australe on olivacine, apparicine, uleine, and guatambine. As the author points out these results are in need of substantiation. [Pg.22]
