Abstract

Atherospermine, the major base of Atherosoerma
moschatum, has been shown to be identical with berbamine
and the phenolic group in this base has been placed
unequivocally.
Sodium in liquid ammonia reductive cleavages have
been used to investigate. structural problems which could
not be resolved by standard degradative methods. In
particular the secondary nitrogen group has been placed
in daphnoline and daphnandrine while more information
has been gained concerning the placement of hydroxyl
groups in aromoline, daphnandrine, daphnoline,isochondrodendrine and.chondrocurine. Observations, on
reductive fission experiments on dauricine and
repanduline have been recorded.
Some stereochemical problems associated with
repandine and okyacanthine have been discussed.
Extractions have been performed using modern techniques
and these procedures have revealed the presence of new
compounds in Berberis vulgaris (isotetrandrine, berberine
oxalamide) and Chondrodendron tomentosum (tomentosine,
N-benzylphthalimide). Extractions on the Daphnandras
have revealed further irregularities in their alkaloid
content.
The results of 4 survey of some Tasmanian plants
for alkaloid-bearing species have been tabulated.
Friedelin together with some other non-basic
compounds have been iSolated'from the bark of Takini,
tree nativeto Surinam South America.
