Physicochemical Variability and Biodiesel Potential of Seed Oils of Two Phenotypes.

Considerable interest is being focused on vegetable oils as fuel. Due to their characteristics being close to diesel and their renewable potential, studies recommend their use for agricultural applications. var.

Comparative chemical study and cytotoxic activity of Uvariodendron angustifolium essential oils from Benin.

This study aimed to compare the chemical composition of volatile extracts obtained by hydrodistillation of leaves, stems, bark and roots of Uvariodendron angustifolium (Engl. & Diels) R. E.

Chemical composition and insecticidal activity of plant essential oils from Benin against Anopheles gambiae (Giles).

Background: Insecticide resistance in sub-Saharan Africa and especially in Benin is a major public health issue hindering the control of the malaria vectors. Each Anopheles species has developed a resistance to one or several classes of the insecticides currently in use in the field. Therefore, it is urgent to find alternative compounds to conquer the vector.

In vitro biological effects of two anti-diabetic medicinal plants used in Benin as folk medicine.

Background: Extracts from Polygonum senegalensis (Polygonaceae) and Pseudocedrela kotschyi (Meliaceae) are two important traditionally used medicinal plants in rural Benin to treat many diseases and notably type 2 diabetes. The aim of the study was to investigate the α-glucosidase inhibition, antioxidant and antibacterial activities of those plants extract: Polygonum senegalensis leaves, and Pseudocedrela kotschyi root.

Methods: Hydro-alcoholic (50%) extracts were analyzed for their phytochemical content and tested for their inhibition potency on α-glucosidase from Saccharomyces cerevisiae.

Potential of the bush mint, Hyptis suaveolens essential oil for personal protection against mosquito biting.

We studied the potential of the essential oil extract from the bush mint, Hyptis suaveolens, for use against mosquito biting under both laboratory and field conditions. In the laboratory, the repellency of various concentrations (1-6%) of the essential oil was assessed against Anopheles gambiae, based on a 15-min landing and biting on treated forearms of volunteers. In the laboratory, the percentage of mosquitoes landing on the forearm was 42, 33, 23, 23, 9, and 2 for 1%, 2%, 3%, 4%, 5%, and 6% essential oil concentration, respectively; and 92 and 91 for the solvent (isopropanol) and untreated control, respectively.
