    Galinsoga parviflora (Cav.): A comprehensive review on ethnomedicinal, phytochemical and pharmacological studies
    (Elsevier, 2023) Ripanda, A.; Luanda, A.; Sule, K. S.; Mtabazi, G. S.; Makangara, J. J.
    Galinsoga parviflora (Cav.) is a member of the Asteraceae family traditionally used for treatment of various ailments such as malaria, flu, cold, colorectal cancer, liver problems and inflammation. The medicinal properties of G. parviflora are due to the presence of various secondary metabolites including flavonoids, saponins, terpenoids and tannins. The literature survey revealed that G. parviflora possesses several pharmacological properties such as antibacterial, antifungal, antioxidant and antidiabetic. This review systematically discusses the potential of G. parviflora for managing medical conditions. The information is collected from various online databases such as Google Scholar, ScienceDirect, Springer, Web of Science, Plant of the World Online and PubMed. Among other information provided in this review, ethnomedicinal uses, phytochemistry and pharmacological activities are discussed extensively. Additonally, the potential benefits, challenges and future opportunities are presented.

    A review on the occurrences of persistent organic pollutants in corals, sediments, fish and waters of the Western Indian Ocean
    (Elsevier, 2021) Miraji, H.; Ripanda, A.; Moto, E.
    Persistent organic pollutants (POPs) present a class of synthetic chemicals that include organochlorine pesticides, polychlorinated biphenyls and dioxins. They are characterized by environmental persistence, transboundary mobility, lipophilicity, and bioaccumulation that may induce fatality especially to top ranked biota due to biomagnification. The oceanic ecosystems are essential pools through which POPs accumulate. Despite the abundance and biotic effects caused by POPs, data on their occurrences as well as the fate of persistent organic pollutants in corals, sediments, fish and waters of the Western Indian Ocean are still scarce. The present review evaluates the status quo, equilibrium distribution of POPs among oceanic ecosystems, and future perspectives of POPs in the Western Indian Ocean. It was observed that some POPs such as DDT and PCBs reported across Africa were more of transformation products than fresh entities. Coastal corals and ocean waters were more contaminated than offshore areas as an indication of terrestrial anthropogenic-based pollution. The Indian Ocean ecosystem, especially fishes, had POPs residuals, whereby DDT and its metabolites were identified as the most frequently occurring POPs. This puts all the interacting ecosystems at high risk through biomagnification. Thus, the reduction of terrestrial contamination and monitoring the trends of POPs in oceanic compartments are necessary for the sustainability of the marine ecosystem.

    Senna singueana (Delile) lock: Ethnomedicinal uses and medicinal properties
    (Elsevier, 2023) Ripanda, A.; Luanda, A.; Mtabazi, G. S.; Makangara, J. J.
    Senna singueana (Delile) Lock is a potential medicinal plant commonly used to mitigate various infectious and non-infectious diseases including malaria, typhoid, gonorrhoea, bilharzia, cancer, epilepsy and ulcer. The phytochemical profile of S. singueana indicates the presence of different phytoconstituents corresponding to the pharmacological properties. The pharmacological potentials such as antibacterial, antifungal, antioxidant, antimalarial and antidiabetics are possessed by S. singueana. This review comprehensively discusses the potential of S. singueana for the mitigation of medical conditions. The information is collected from various online databases such as Google scholar, ScienceDirect, Springer, Web of Science and PubMed. Among other information, ethnomedicinal uses, phytochemistry, pharmacology and mechanisms of action are extensively presented. A review concluded by highlighting the challenges and potential future outlooks.
