title: New Sesquiterpene Glycosides from the Leaves of Eriobotrya japonica.
abstract: One new sesquiterpene glycoside, named nerolidol-3-O-α-L-rhamnopyranosyl-(1 --> 6)-β-D-glucopyranoside (1), along with one novel natural product nerolidol-3-O-α-L-rhamnopyranosyl-(1 --> 2)-[α-L-rhamnopyranosyl-(1 --> 6)]-β-D-glucopyranoside (2) and two known sesquiterpene glycosides (3-4), were isolated from the leaves of Eriobotrya japonica (Thunb.) Lindl.. Their structures were elucidated on the basis of 1D, 2D NMR and HR-MS data. The chemotaxonomic significance of this type of constituents was discussed.
