Vinca herbacea

The presence of vincamajine in Vinca herbacea has been confirmed.44 7... [Pg.200]

Antirhine (C19H24N2O, mp 112-114°, [ajj, —2° (CHCI3)), has been isolated from Antirrheaputaminosa (F. v. Muell.) Bail, and the structure CXXIII has been proposed for it (61). Vinca herbacea yielded hervine (C23H28N2O4, mp 173-175°, [a]p —93° (EtOH)) for which the structure CXXIV has been assigned (62). [Pg.183]

Lochnerinine (LXXXIX) was shown to be an aromatic methoxy-lochnericine by the 30 mass unit shift of the indolic peaks in its mass spectrum as compared with those of lochnericine 22). Reduction with zinc and acetic acid gave a dihydroindole whose UV-spectrum was closest to that of 7 -methoxyhexahydrocarbazole and the methoxy group was therefore placed at the 16-position 21, 22). Lochnerinine is the epoxide of 16-methoxy-( — )-tabersonine with which it co-occurs in Vinca herbacea 22a). [Pg.233]
