Phytochemical investigation of the rhizomes of Paris polyphylla var. stenophylla led to the isolation of two new highly oxygenated spirostanol saponins, named paristenosides A (1) and B (2), together with seven known compounds. Their structures were established mainly on the base of NMR spectroscopic techniques and mass spectrometry, as well as chemical methods. In addition, the cytotoxicity of the two new saponins was tested.
