Abstract
Seven oleanane-type glycosides were extracted and isolated by various chromatographic methods from the roots of Weigela x “Bristol Ruby” (1–7), six previously undescribed (1–6) and a known one (7). Their structures were assigned by spectroscopic analysis mainly 2D NMR and mass spectrometry (ESIMS). Selected triterpenoid glycosides (1–3, 6, 7) displayed a good cytotoxic activity against a mouse colon cancer cell line CT26.
