Biological Activities
Terminalia avicennioides demonstrates significant medicinal potential through its diverse biological activities. Research indicates that this plant possesses antidiabetic properties, specifically by modulating the efflux ratio of glibenclamide in intestinal models. Furthermore, the species exhibits strong antioxidant capacity, which was validated through various assays such as DPPH and ABTS. These antioxidant effects are largely attributed to the presence of key phenolic compounds, including quercetin, isorhamnetin, and ferulic acid. Together, these findings highlight the plant's value as a source of bioactive molecules for potential phytomedicinal applications.
Compounds
Terminalia avicennioides has emerged as a significant subject of study due to its promising medicinal properties against malaria. Research conducted on medicinal plants from Burkina Faso revealed that the MeOH/H2O leaf extract of this species possesses strong antiplasmodial activity. Through a process of bioguided fractionation, scientists successfully isolated ellagic acid from the plant's ethylacetate extract. This specific compound demonstrated exceptional potency, showing an IC50 of 0.2 μM against the Plasmodium falciparum parasite. Furthermore, both the plant extract and the identified ellagic acid exhibited strong antioxidant capabilities, highlighting their therapeutic potential.
Conditions
Terminalia avicennioides demonstrates significant medicinal potential by inhibiting the migration of B16-F10 melanoma cells. The plant also exhibits potent antifungal properties, effectively treating infections caused by Candida albicans and Candida glabrata. In the realm of antiparasitic research, its leaf extracts have been shown to treat Leishmania mexicana mexicana (Lmm). Furthermore, both the water and ethanol extracts of this species are effective in treating methicillin-resistant Staphylococcus aureus (MRSA). These diverse biological activities highlight its value in addressing various bacterial, fungal, and parasitic challenges.
Preparations
Terminalia avicennioides is prepared as aqueous extracts to test its effects on glutathione levels and P-glycoprotein efflux activity. This plant is also prepared as MeOH/H2O leaf extracts, which have demonstrated significant antiplasmodial activity against Plasmodium falciparum. Various studies utilize Terminalia avicennioides prepared as extracts to evaluate its potential as a chemoprotective agent or as an antimicrobial therapy. Furthermore, the plant is prepared as methanol extracts of different parts of each plant, specifically stem barks and fruits, to investigate its antitrypanosomal effects. Finally, Terminalia avicennioides is prepared as water and ethanol extracts to provide a scientific basis for its traditional use against MRSA-associated diseases.
Parts used
Terminalia avicennioides is a medicinal plant species that offers significant therapeutic potential through its various anatomical components. Research has demonstrated that the leaf of this plant contains extracts with potent antiplasmodial and antioxidant properties, specifically through the isolation of ellagic acid derivatives. Beyond its leaves, the round fruit of the species has also been investigated for its medicinal value in traditional practices. Studies on methanol extracts from these fruits have shown that they possess trypanostatic effects against Trypanosoma brucei brucei. Collectively, these findings highlight the importance of both the leaves and fruits of Terminalia avicennioides as important sources for discovering new antiparasitic compounds.
