Toxicity, Antibacterial, and Phytochemical Analyses of Pierre Extracts.

Medicinal plants are traditionally used in Gabon to treat several types of illnesses. The study's purpose was to determine the toxic, antibacterial, and anti-inflammatory effects of Pierre extracts and to characterize their phytochemical compounds. Toxicity was evaluated on frog tadpoles ( Hallowell).

Structure elucidation of a new lanostane triterpene from Gabonese Ganoderma orbiforme fruiting bodies.

The structure and complete nuclear magnetic resonance (NMR) assignments of orbifomitellic acid, a novel lanostane triterpene isolated from the fruiting bodies of a Gabonese Ganoderma orbiforme (Polyporaceae), are reported. Within the vast catalogue of lanostanes documented from Ganoderma spp., orbifomitellic acid is the first disclosing a -COOH group at C-4.

Diabetes in Sub-Saharan Africa: Distribution Based on Social Status in Libreville (Gabon).

Objective: Many researchers continue to believe that urbanization is a major contributor to diabetes. We seek to demonstrate that the social status associated with urbanization has an impact on the prevalence of diabetes in Libreville, Gabon in sub-Saharan Africa.

Methods: Our study was conducted in Libreville, the capital of Gabon; the city has a population of 397,000.
