Vincamajine

Sarpagine-Ajmaline-Picraline Group. Vincamajine and quebrachidine have been found to occur in the leaves and stem bark of Alstonia odontophora,59 normacusine B occurs in Strychnos rubiginosa,ss and vellosimine in Rauwolfia vomitoria.lla R. volkensii contains quaternine, nortetraphyllicine, peraksine,... [Pg.170]

Sarpagine-Ajmaline-Picraline Group. Ajmaline and pelirine are among the constituents of the roots of Rauwolfia cambodiana,60 and ajmaline, 12-methoxy-ajmaline, vomalidine, norajmaline, rauvomitine, tetraphyllicine, and ajmaline 17-O-trimethoxybenzoate occur in the roots of R. obscura.61 Vincamajine has been... [Pg.182]

Sarpagine-Ajmaline-Picraline Group. (+)-Quebrachidine (142) is one of the minor alkaloids of the root bark of Cabucala striolata, and of the stem and root bark of C. torulosa, which also contains (-)-vincamajine (143). O-Trimethoxy-cinnamoylvincamajine (144), a known alkaloid, and six new vincamajine derivatives, have been extracted from the aerial parts of Alstonia lanceolifera. Three of the new alkaloids are 10-methoxy-3,4,5-trimethoxycinnamoylvincamajine (145), 10-hydroxy-3,4,5-trimethoxycinnamoylvincamajine (146), and 10-methoxyvinca-majine (147) the other three alkaloids are suspected to be the trimethoxybenzoyl... [Pg.215]

A new vincamajine ester, 4 -hydroxy-3, S -dimethoxybenzoylvincamajine (90) was obtained from the roots of Alstonia angustifolia, in addition to nine other known alkaloids, alstonerine, alstophylline, vincamajine, villalstonine, macralstonine, pleiocarpamine, macrocarpamine, norfluorocurarine and 11-methoxyakuammicine [84]. The UV spectrum of 90 was similar to... [Pg.340]

In reference (124b) compound 71 is erroneously referred to as vincamajine Ar(l)-tri-(7-methylgallate instead of norvincamajine A (l)-tri-<7-methylgaIlate. [Pg.18]

Oxidation of vincamajine (43) with CrOj in pyridine leads to voachalotinal (148) I3I, 170) (Scheme 15). [Pg.44]
