Biological Activities
Landolphia owariensis has demonstrated significant antiplasmodial activity, providing a scientific basis for its traditional use in treating malaria in southeast Nigeria. Research conducted on Plasmodium berghei-infected mice shows that leaf extracts can effectively reduce parasitemia across early, established, and residual infection stages. Specifically, the methanol fraction of the leaf extract exhibited the highest level of suppressive activity and improved survival rates in the study subjects. Beyond reducing parasite levels, the treated mice also showed significant weight gain and a marked decrease in mortality compared to untreated groups. These findings, supported by the presence of bioactive compounds like alkaloids and flavonoids, validate the plant's potential as a natural antimalarial agent.
Compounds
Conditions
Landolphia owariensis exhibits significant neuroprotective properties by treating alcohol-induced cerebellar neurodegeneration and general neurodegeneration. Research demonstrates that the plant attenuates alcohol-induced cerebellar degeneration by alleviating oxidative stress and stabilizing neurofilament protein expression. Additionally, the bioactive compounds found within its stringy seed pulp provide essential anti-inflammatory activity. These constituents also contribute to the plant's medicinal profile through effective anti-colon cancer action. Together, these diverse biological activities highlight the therapeutic potential of the species.
