A new triterpenoid tetrasaccharide from the root of Scrophularia ningpoensis

 A new oleanane-type triterpenoid glycoside, 3β-O-(β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl (1→4)-β-D-glucopyranosyl-(1→3)-β-D-fucopyranosyl-11, 13(18) diene-olean-23α, 28 diol (1), along with three known phenylethyl glycosides (2−4), was isolated from the root of traditional Chinese medicine Scrophularia ningpoensis.  Among them, compounds 2 and 3 were obtained from Scrophularia genus for the first time.  The structure of compound 1 was elucidated on the basis of spectroscopic method including 1D, 2D NMR and HR-ESI-MS.
