title: Silenorubicosides A-D, triterpenoid saponins from Silene rubicunda.
abstract: Four novel triterpenoid saponins, silenorubicosides A-D (1-4), together with four known saponins were isolated from the roots of Silene rubicunda. Their structures were established on the basis of spectroscopic analysis, including extensive 1D and 2D NMR (DQF-COSY, TOCSY, HETCOR, HMBC, and phase-sensitive NOESY) studies and chemical degradation.
