Africa is famous for its floral biodiversity, exploited by local people for therapeutic purposes. However, such plants need to be scrutinised scientifically for the presence of bioactive compounds and possible biological properties. This study attempts for the first time to highlight the

The methanol extracts of three Macaranga species (M. denticulata, M. pruinosa, and M. gigantea) were screened to evaluate their total phenolic contents and activities as cholinesterase inhibitors, nitric oxide (NO) production inhibitors, tyrosinase inhibitors, and antioxidants. The bark of M.

Propolis, a resinous substance, is collected from plants and processed by honeybees to seal holes and cracks in beehives, protecting them from microbial infection. Based on the plant source and geographical location, propolis is categorized into seven groups. Of these, Pacific propolis, found in the
