Ursane-Type Triterpenes, Phenolics and Phenolic Derivatives from Leaf.

is a hemi-parasitic plant used in African ethnomedicine for the management of microbial infections, rheumatic pain and tumors amongst others. We report the isolation and characterization of eight compounds with their antioxidant and antimicrobial activities. The air-dried powdered leaf was macerated in EtOH/H0 (4:1).

Evaluation of ethnomedical claim III: anti-hyperglycemic activities of Gongronema latifolium root and stem.

Background: The insulinotropic activity of the combined root and stem of Gongronema latifolium (Asclepiadaceae) was evaluated to justify its African ethnomedicinal use in the management of diabetes.

Methods: A methanolic extract and its chromatographic fractions (A1 -A6 ) were tested for glucose-reducing and in vitro insulin-stimulating abilities using glucose-loaded rats and INS-1 cells, respectively. In vivo insulin-releasing activities for the significantly (P<0.

In-vitro evaluation of anti-trichomonal activities of Eugenia uniflora leaf.

Eugenia uniflora, used ethnomedically in some tropical countries as an anti-infective, has shown anti-malarial and anti-trypanocidal activities. Therefore using bioactivity guided fractionation, anti-trichomonal activity of E. uniflora leaf was investigated.

Tetrapleura tetraptera: molluscicidal activity and chemical constituents.
