Antidiabetic and antioxidant effects of L. in alloxan-induced diabetic rats.

Background: contains a high amount of antioxidant phytochemicals that probably account for its wide use as food and medicine in the traditional communities of West Africa.

Methods: The study evaluated the modulatory role of methanol extract of Croton lobatus leaf on alloxan-induced diabetes and associated cardiovascular complications. Male rats were randomly selected and assigned to one of six groups (A to F) of eight animals each: A (distilled water); B (corn oil); C (Alloxan); D (Alloxan + 100 mg kg-1 Croton lobatus); E: (Alloxan + 200 mg kg-1 C.

The ethnobotanical, phytochemical and mineral analyses of phragmanthera incana (klotzsch), a species of mistletoe growing on three plant hosts in South-Western Nigeria.

Mistletoe is collected wildly on various plants and Phragmanthera incana is noted to grow on different plant hosts. This study was designed to carry out the ethnobotanical survey, phytochemical and mineral analyses of Phragmanthera incana, a species of mistletoe growing on three plant hosts namely Cocoa (Theobroma cacao), Kolanut (Cola nitida) and Bush mango (Irvingia gabonensis). Mistletoe samples were identified at the Forestry Research Institute of Nigeria Herbarium.

Chemical composition, toxicity and antioxidant activities of essential oils of stem bark of Nigerian species of guava (Psidium guajava Linn.).

Essential oil from the stem bark of Nigerian species of of the family Myrtaceae was obtained by hydro-distillation using an all-glass Clavenger apparatus. GC and GC/MS analysis were carried out on the essential oil and was found to contain 62 compounds constituting 99.98 % of the total oil composition.
