Mareya micrantha Müll. Arg. (Euphorbiaceae) is a plant used in the Ivorian traditional medicinal system for various medical properties such as laxative, oxytocic, intestinal infectious diseases, malaria, etc.

Spectroscopic data of new cassane diterpenoids from the root bark of .

The data are related to the research article entitled ''New cassane diterpenoids from the root bark of Erythrophleum suaveolens'' (Jacques et al., 2019). The article provides method of purification and data to determine structure of two novel cassane diterpenoid amines: 3β-hydroxy-3-methylbutanoyloxy-6α-hydroxy-nor-cassamine (1) and 3β-hydroxy-3-methylbutanoyloxy-erythrosuamine (2).

Three novel non-nitrogenous cassane diterpenoids from (Guill. et Perr.) Brenan (Fabaceae).

During our research to contribute to the elucidation of the chemical composition of the root bark of , six non-nitrogenous cassane diterpenoids () were isolated and identified. Of these secondary metabolites, three have never been previously described: Cassan-13,15-dien-3-oxo-17-oic acid (), Cassan-15-en-[7,17]-γ-lactone () and 6-hydroxy-cassamic acid (). The other are known but, never isolated from the root barks of (Fabaceae): Cassan-13,15-dien-17-oic acid (), hydroxycassamic acid methyl esther () and cassamic acid ().

Three new natural compounds from the root bark essential oil from Xylopia aethiopica.

Introduction: In the course of on-going work on the characterisation of aromatic plants from the Ivory Coast we investigated the composition of the root oil from Xylopia aethiopica.

Objectives: The aim of this work was to investigate the chemical composition of X. aethiopica root oil and elucidate the structure of two new compounds.
