Abstract:
Ten compounds were isolated and purified from the dichloromethane fraction of Trichosanthes tricuspidata roots by silica gel and ODS column chromatographies. Their chemical structures were identified on the basis of their physical and chemical properties as well as the spectral data. These isolated compounds were elucidated as khekadaengoside O(1), a new hexanorcucurbitane glycoside, together with nine known compounds, including khekadaengoside C-E, K(2-5), cucurbitacin J-2-O-β-glucopyranoside(6), cucurbitacin K-2-O-β-glucopyranoside(7), cucurbitacin B, J, K(8-10). In addition, the anti-tumor activity of compounds 1-10 were evaluated in hepatocellular carcinoma BEL-7402 cell line. Among them, compounds 8-10 showed potent antitumor activity.
