  • Title: Triterpenoid saponins from Gynostemma pentaphyllum.
    Author: Shi L, Cao JQ, Shi SM, Zhao YQ.
    Journal: J Asian Nat Prod Res; 2011 Feb; 13(2):168-77. PubMed ID: 21279881.
    Abstract:
    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.
