Abstract
An investigation of two species of Nuxia (Buddlejaceae) showed
that this genus is characterised by the presence of the
eight-carbon iridoid glucoside unedoside and/or its derivatives.
From N. floribunda was isolated unedoside, nuxioside
(6-O-a-L-rhamnopyranosyl-unedoside) and
2''-acetyl-3''-cinnamoyl-nuxioside, while from N. oppositifolia
was obtained 2''-acetyl-3''-benzoyl-nuxioside. Verbascoside was
isolated from both plants. The biosynthesis of unedoside in N.
floribunda was investigated and deoxyloganic acid was shown to be
a precursor. The taxonomic position of Nuxia and Buddlejaceae is
discussed.
