Four new dammarane-type triterpene saponins, 1–4, were isolated from the aerial parts of Gynostemma pentaphyllum (Thunb.) Makino. Their structural elucidations were accomplished mainly on the basis of spectroscopic methods, such as IR, HR-TOF-MS, and NMR. Compounds 1–4 showed moderate cytotoxic activities against cancer cell lines HL-60, Colon205, and Du145 in vitro.
