Ten triterpene saponins have been isolated from a MeOH extract of the leaves of Ilex oblonga. In their structures, six new triterpenoid saponins were named as oblonganosides H-M (2, 4, 5, and 8-10). All structures were elucidated on the basis of spectroscopic analysis. Among the triterpenoid saponins, three compounds (7, 8, and 10) showed obvious activities in inhibiting multiplication of the tobacco mosaic virus (TMV).
