(P. Beauv.): Investigation of the Chemical Variability and In Vitro Anti-inflammatory Activity of the Leaf Essential Oil from the Ivorian Species.

The variability of chemical composition of the leaf essential oil (EO) from , a climbing liana growing wild in Ivory Coast, was investigated for the first time. The in vitro anti-inflammatory activity was also evaluated. Thirty oil samples were isolated from leaves collected in three forests of the country and analyzed using a combination of Column Chromatography (CC), Gas Chromatography with Retention Indices (GC(FID)), Gas Chromatography-Mass Spectrometry (GC-MS), and Carbon-Nuclear Magnetic Resonance (C-NMR).

Chemical composition of root and stem bark essential oils from Ivorian : structural elucidation of a new natural germacrone.

The root and stem bark essential oils from Isolona dewevrei (Annonaceae), growing wild in Côte d'Ivoire, were investigated for the first time, using a combination of chromatographic [CC, GC(RI)] and spectroscopic [MS, C-NMR] techniques. A new natural germacrone was isolated by repetitive column chromatography carried out on a stem bark oil sample. Its structure was elucidated as germacra-1(10),4(15),5-trien-8-one by 1 D, 2 D-NMR and QTOF-MS.

New Natural Oxygenated Sesquiterpenes and Chemical Composition of Leaf Essential Oil from Ivoirian (De Wild. & T. Durand) Engl. & Diels.

This study aimed to investigate the chemical composition of the leaf essential oil from Ivoirian . A combination of chromatographic and spectroscopic techniques (GC(RI), GC-MS and C-NMR) was used to analyze two oil samples (S1 and S2). Detailed analysis by repetitive column chromatography (CC) of essential oil sample S2 was performed, leading to the isolation of four compounds.

Composition and Intraspecific Chemical Variability of Leaf Essential Oil of Laggera pterodonta from Côte d'Ivoire.

The chemical composition of 44 leaf oil samples of Laggera pterodonta (DC.) Sch.Bip.

Composition and Chemical Variability of Enantia polycarpa Engl. & Diels Leaf Essential Oil from Côte d'Ivoire.

The composition of Enantia polycarpa Engl. & Diels leaf essential oil has been investigated for the first time using a combination of chromatographic and spectroscopic techniques. The compositions of 52 leaf essential oil samples have been subjected to statistical analysis, hierarchical cluster analysis (HCA) and principal component analysis (PCA).

Chemical Investigation on Leaf, Flower and Fruit Oils of Lantana camara from Côte d'Ivoire.

The compositions of essential oil obtained from leaves, flowers and fruits of Lantana camara L. growing in wild at Cte d'Ivoire, were investigated by GC and ¹³C NMR. Thirty-seven compounds accounting for 88.

Chemical Variability of Ivoirian Xylopia rubescens Leaf Oil.

Forty-two essential oil samples were isolated from leaves of Xylopia rubescens harvested in three forests of Southern Ivory Coast. All the samples have been submitted to GC-FID and the retention indices (RIs) of individual components have been measured on two capillary columns of different polarity. In addition, 20 oil samples, selected on the basis of their chromatographic profile, were also analyzed by C-NMR and 24 components (78.

Composition and Chemical Variability of Ivoirian Xylopia staudtii Leaf Oil.

The chemical composition of a leaf oil sample from Ivoirian Xylopia staudtii Engler & Diels (Annonaceae) has been investigated by a combination of chromatographic [GC(RI)] and spectroscopic (GC-MS, 13C NMR) techniques. Thirty-five components that accounted for 91.8% of the whole composition have been identified.

Chemical variability of Xylopia quintasii Engl. & Diels leaf oil from Côte d'Ivoire.

The chemical composition of 42 essential-oil samples isolated from the leaves of Xylopia quintasii harvested in three Ivoirian forests was investigated by GC-FID, including the determination of retention indices (RIs), and by (13) C-NMR analyses. In total, 36 components accounting for 91.9-92.

Chemical variability of the leaf essential oil of Xylopia aethiopica (Dunal) A.Rich. from Côte d'Ivoire.

The chemical composition of 48 essential-oil samples isolated from the leaves of Xylopia aethiopica harvested in six Ivoirian forests was investigated by GC-FID and (13) C-NMR analyses. In total, 23 components accounting for 82.5-96.

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.
