Laboratoire de Chimie et de Valorisation des Produits Naturels, Faculty of Sciences, University of Antananarivo, Madagascar.
Background: The aerial parts of Baker and Baker are used by the population of the Vakinankaratra and Itasy regions (Madagascar) to treat breathing difficulty, fever and/or headache, wounds, and sores.
Purpose: This work aimed to characterise plant materials from . and to report i) chemical composition, ii) antimicrobial properties, and iii) antioxidant capacity of the essential oils extracted from the aerial parts of these species.
Article Synopsis
- Researchers isolated five new compounds called omphalines A-E from the leaves and twigs of Omphalea oppositifolia, along with a known compound using chromatography methods.
- Omphaline A's structure was identified as a specific type of diterpenoid, characterized by unique double bonds and hydroxy groups.
- The absolute configuration of omphaline A was confirmed by comparing its experimental electronic circular dichroism (ECD) spectrum with calculated ones.

From the stem bark of a Madagascan endemic plant, Millettia richardiana Baill., lonchocarpenin and betulinic acid were isolated and their structures established by spectroscopic methods. The analysis of dichloromethane fractions suggested the presence of beta-amyrin, lupeol, palmitic acid, linoleic acid and stearic acid.
