摘要
A new triterpenoid saponin, silenoviscoside F (1), was isolated from the roots of Silene viscidula, together with three known saponins, dianchinenoside D (2), sinocrassuloside I (3) and sinocrassuloside II (4). The structure of compound 1 was elucidated by spectroscopic data, GC-MS and chemical methods. The structures of compounds 2-4 were determined on the basis of spectroscopic data comparison with the literature values, which were isolated from the genus Silene for the first time.
