Ervatamia heyneana

Finally, two phenolic derivatives of coronaridine were isolated 10-hy-droxycoronaridine (98, C21H26N203) from the wood and stem bark of T. hey-neana (Ervatamia heyneana) (128) and 11-hydroxycoronaridine (99, amorphous, [a]D —34°) from T. attenuata (47). Both gave characteristic UV spectra with bathochromic shifts on addition of alkali, in agreement with the proposed... [Pg.91]

The corresponding A4-oxide (132, C22H26N205, [a]D +86.6°) isolated from T. heyneana (Ervatamia heyneana) shows loss of 16 amu from M+ and subsequent fragmentation similar to that of other 3,6-oxidovoacangines (128). Skeletal... [Pg.92]

The first extractions of Strempeliopsis strempelioides K. Schum. (Family Apo-cynaceae), from Cuba, reveal that it is rich in alkaloids. The leaves and stem bark contain, amongst others, (+)-tubotaiwine and (+)-condylocarpine, and the stem bark also contains (-)-apparicine.80 Apparicine (pericalline) also occurs, together with O-acetylvallesamine, 19,20-dihydrocondylocarpine, and eleven other alkaloids, in the wood and stem bark of Ervatamia heyneana (Wall.) T. Cooke,81 and... [Pg.174]

In addition to Camptotheca acuminata (Nyssaceae), camptothecine (6) has been found in Nothapodytes (Mappia) foetida and Merilliodendron megacarpum (Icacinaceae), Ophionhiza mungos (Rubiaceae), and Ervatamia heyneana (Apocynaceae) (Cordell, 1981). This distribution is of considerable interest to plant systematists and phylogenists, as it reflects the same dichotomy seen in the distribution of other types of monoterpene iridoids. [Pg.648]

Nothapodytes foetida (Icacinaceae) (55, 56). From Ophiorrhiza mungos (Rubi-aceae), camptothecin and 10-methoxycamptothecin have been obtained, and from Ervatamia heyneana (Apocynaceae), camptothecin and 9-methoxycamptothecin (59). From Merrilliodendron megacarpum (Icacinaceae), camptothecin and 9-methoxycamptothecin have been isolated (3). Table 5.2.5 lists yields from various plants. [Pg.245]
