Abstract: Calpurnia aurea plant belongs to in the fabaceae family and in the general of Calpurnia is a widely consumed medicinal plant in east Africa such as Ethiopia and Eritrea. It used to treat diseases like amoebiasis, giardiasis, dysentery, syphilis, malaria, exoparasite, diarrhea and snake bite. Many scientific papers available about it’s phytochemical and pharmacological activities. This review was focused on the Ethnobotay, phytochemistry and the biological activities of Calpurnia aurea plant using different scientific articles, books and reports available online in academic searching sites such as Google scholar, PubMed, Scoups, ProQuest and Web of science. Based on the review all parts of the plant reported to have secondary metabolites such as flavonoids, terpenoids , alkaloids, glycosides, tannins and steroids and, biological activities such as antioxidant, antibacterial, anticancer, antimalarial, anti-diarrheal, antiextoparasite and insecticidal activities. Bioactive chemical compounds also reported from stem, leaves, bark and seeds of Calpurnia aurea plant in different classes such as alkaloids, flavonoids, glycosides and terpenoids. Based on the information gathered from the chemical constituent and pharmacological properties of the plant part Calpurnia aurea is confirmed the traditional medicinal use but further work is required related to isolation of more bioactive compounds and to investigate biological activities in advanced techniques including Insilco methods to contribute for modern drug discovery.

Abstract: The rapid acquisition of multidrug-resistant (MDR) phenotypes by bacteria creates life-threatening complications in infection control. Accordingly, this study aims to investigate the antibacterial activity of the methanol extract of Talinum fruticosum leaves and its interaction effects with antibiotics against MDR Gram-negative bacteria. The broth microdilution method was used to evaluate the antibacterial activity and antibiotic-resistance modulation effects of the extract. The interaction between antibiotics and T. fruticosum leaf extract (TFLE) was conducted using the checkerboard assay. Phytochemical screening was assessed using standardized qualitative tests. TFLE displayed low antibacterial activity, with MICs ranging from 512 to 2048 µg/mL against the tested bacteria. Interestingly, TFLE at its subinhibitory concentration (MIC/8) enhanced the efficacy of antibiotics by 2-to 64-fold, particularly tetracycline, doxycycline, imipenem, kanamycin, and ciprofloxacin, against at least one of the examined MDR bacteria. In addition, TFLE displayed a synergistic effect (ƩFIC < 0.5) with kanamycin and doxycycline against K. pneumoniae K2 and E. aerogenes EA298. The phytochemical screening indicated that TFLE contained flavonoids, saponins, tannins, terpenoids, phenols, and anthocyanins. Overall, this study shows that T. fruticosum leaf extract could be used in combination with commonly used antibiotics to fight infections involving MDR bacteria. Therefore, further studies are needed to identify in this plant a likely nontoxic antibiotic modulator.

Abstract: Ethnomedicinal relevance: Medicinal plants are a source of many potent drugs since they possess diverse phytochemical compounds. Studies on different plant life forms are voluminous, except trees. No single study has been done on tree species used to manage diseases in different regions of Uganda from 1995 up to 2023. Aim of the study: This review aimed to compile tree species used to manage different diseases and disease symptoms in various areas in Uganda. Materials and methods: The review examined 20 studies with ethnobotanical surveys done in Uganda. Data extraction focused on plant families and species, plant parts used, preparation methods and routes of administration, and the region in Uganda where the ethnobotanical field surveys were conducted. Results: 151 tree species from 52 families were identified. Leaves (34.7%) were highly depended on followed by bark (32.0%) and roots (19.7%) were also commonly used. The majority of the herbal remedies were prepared by decoction and taken orally. In regard to disease management using medicinal tree species, the diseases that were prevalent and posing public health concerns were malaria, diarrhea, breast cancer, syphilis, HIV/ AIDs, ulcers, tuberculosis, and skin infections. Conclusion: Many tree species in Uganda are used to manage several ailments. However, other tree species with medicinal importance remain undocumented and yet some of them are being destroyed by anthropogenic activities. Efforts to ensure sustainable harvesting of these medicinal tree species are thus required.
