ABSTRACT: Uvaria tortilis is a lianescent annonaceous species endemic to the
Côte d’Ivoire where it is used
to treat amenorrhea and as uterotonic. Thus, the MeOH crude extract of
its stem barks was investigated in order to determine the chemical composition.
A new C-benzyl hydroxlated, uvriatortilisin (1), together with six known
compounds, dichamanetin (2), β-sitosterol
(3), stigmasterol (4), chamanetin (5), uvaretin (6)
and (-)-epicatechin (7), were isolated. Structure of these compounds was
elucidated using spectroscopic techniques, including IR, UV, MS and NMR (1D and
2D). Certain compounds could be considered to have chemotaxonomic value.
