• Cytotoxic / Anticancer Activity: Study investigated the cytotoxic effects of various extracts from 16 Bangladesh medicinal plants, including Cynometra ramiflora, against human gastric, colon and breast cancer cell lines. CM exerted low toxicity against mouse fibroblast but selective cytotoxicity against different cancer cell lines. (1)
• Phytochemical / Antibacterial: Phytochemical screening yielded gums, reducing sugars, tannins and saponins. Study showed moderate antimicrobial activity against E coli, Staph epidermis, Shigella dysenteriae, Enterococci, S sonnei, S aureus, S typhi, S flexneri and Vibrio cholera. (2)
• Blood Glucose Lowering: Extract of Cynometra ramiflora was found to significantly lower the postprandial blood glucose level of the sucrose loaded rats significantly. (3)
• Neuropharmacological / Antibacterial / Antinociceptive: Crude methanolic extract of bark of C. ramiflora was evaluated for neuropharmacological, antibacterial and antinociceptive properties. Results showed depressant central nervous system effects. Toxicity testing showed safety up to 1600 mg/kbw. Extract also showed significant antibacterial activity against V. cholera, S. typhi, S. aureus. The methanolic extract showed significant inhibition of writhing in the acetic acid-induced writhing model in white albino mice. (4)
