title: A new triterpenoid tetrasaccharide from the root of Scrophularia ningpoensis.
abstract: A new oleanane-type triterpenoid glycoside, 3beta-O-(f-D-xylopyranosyl-(1-->2)-[beta-D-glucopyranosyl (1-->4)-beta-D-glucopyranosyl-(1 -->3)]-beta-D-fucopyranosyl-11, 13(18) diene-olean-23alpha, 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.
