Four new cucurbitane-type triterpenes were isolated from the fruit of Momordica charantia L. The structures of the new compounds were identified based on HR-ESI-MS and 1D- and 2D-NMR spectroscopic methods. The cytotoxicity of the isolated compounds was evaluated using three human cancer cell lines, HeLa, Caco2, and U87. Compound 3 exhibited significant cytotoxic activity against HeLa cells with an ICvalue of 11.18 μM. Additionally, the cytoprotective activity of these compounds was determined in vitro against HO-induced pancreatic injury. The results revealed that all the compounds obtained possess cytoprotective effects against HO-induced injury in MIN6β-cells at a concentration of 10 μM.
