Abstract

A detailed phytochemical examination of the alkaloid content
of two species of the family Elaeocarpaceae - Aristotelia serrata
W.R.B. Oliver and Aristotelia fruticosa Hook F. - has been
undertaken.
A new group of indole alkaloids has been isolated from the
abovementioned species. Of the sixteen bases obtained, one had
been described previously and was reisolated from Aristotelia
serrata. Spectroscopic and chemical evidence for the structures
of the fifteen new minor alkaloids are presented. X-ray
crystallographic studies confirmed the structures of two of them,
and established the relative stereochemistries. In one case, the
structural assignment was confirmed by synthesis. The absolute
stereochemistries of altogether six alkaloids have been established
through chemical correlations.
A possible biosynthetic scheme for the Aristotaia alkaloids is
presented.
A preliminary investigation of one species of the family
Menispermaceae - Pachygone vieillardii - has been made, and the
results appear in Appendix-l. Of the five alkaloids isolated from
this species, one appears to have a bisbenzylisoquinoline type of
structure. Tentative evidence is presented to support a proaporphine-type
structure for two further alkaloids, and a morphinane-type
structure for each of the remaining pair of alkaloids.
