Objective: This study aimed to comprehensively evaluate the chemico-pharmacological properties of methanolic extractives derived from Cyanometra ramiflora leaves, encompassing a spectrum of activities including cytotoxic, thrombolytic, membrane-stabilizing, antioxidant, antidiarrheal, hypoglycemic, and analgesic effects. Methods: Phytomolecules were identified using Gas Chromatography-Mass Spectrometry (GC-MS), while antioxidant activity was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and total phenolic content tests. Cytotoxicity was determined through the brine shrimp bioassay, while thrombolytic activity was evaluated via clot lysis assays, and membrane-stabilizing effects were investigated for potential anti-inflammatory properties. In-vivo experiments using mice were conducted solely with the methanolic extract to assess central and peripheral analgesic, hypoglycemic, and antidiarrheal properties. Results: The presence of 47 compounds in the methanolic extract, with tetratriacontyl pentafluoropropionate (9.25%), pentatriacontane (8.75%), and 2-methylhexacosane (5.9%) being predominant. The dichloromethane-soluble fraction exhibited the highest cytotoxicity, with a 50% lethal concentration (LC50) of 11.05 µg/mL. Both petroleum-ether and methanol-soluble fractions demonstrated more than 50% lysis in thrombolytic activity assays. Under hypotonic and heat-induced conditions, the ethyl acetate and dichloromethane-soluble fractions of C. ramiflora significantly reduced erythrocyte hemolysis. Notably, the methanol-soluble fraction exhibited significant antioxidant potential with 50% inhibitory concentration (IC50) of 17.71 μg/mL compared to the standard EDTA (IC50 = 75.94 μg/mL). The hypoglycemic investigation revealed a 63.73% reduction at 90 min with a 600 mg/kg dose, while mild antidiarrheal activity was observed with a 37.5% reduction in diarrhea at 4 h intervals. Significant analgesic effects were demonstrated in both central and peripheral tests, with a 68.53% reduction in writhing during the peripheral test and an average tail immersion time of 5.38 s at 90 min. Conclusion: C. ramiflora leaves show promise as natural sources for various pharmacological activities, including cytotoxicity, thrombosis, inflammation, antioxidant, hypoglycemic, and analgesic effects. However, further comprehensive research is recommended to elucidate the precise mechanisms of action and analyze the phytochemical composition of C. ramiflora plants.
