Isoquinoline Alkaloids from Monanthotaxis trichocarpa
Abstract
Twelve
secondary
or
tertiary
alkaloids
and
two
quaternary
alkaloids
were
isolated
from
the
twig
of
Monanthotaxis
trichocarpa
(Annonaceae).
Their
structures
were
identified
as
(+)-laurotetanine
(1),
(+)-N-methyllaurotetanine
(2),
(+)-isoboldine
(3),
S-actinodaphine
(4),
(+)-N-methylaetinodaphine
(5),
(-)-3-hydroxynornuciferine
(6),
(-)-asimilobine
(7),
(-)-anonaine
(8),
(+)-reticuline
(9),
(+)-coclaurine
(10),
(-)-coreximine
(11),
O-discretamine
(12),
(+)-magnoflorine
(13)
and
dehydrodiscretamine
(14).
These
were
confirmed
as
constituents
of
this
plant
for
the
first
time.
