title: Five natural carbohydrates from the leaves of Sauropus rostratus.
abstract: Three new hexose derivatives (1-3), together with two known ones (4,5), were isolated from the leaves of Sauropus rostratus. The structures of new compounds were elucidated on the basis of the spectroscopic methods including 1D and 2D NMR (HSQC, (1)H-(1)H COSY, HMBC and NOESY) and HR-MS analyses. The absolute configurations of three new compounds were established by the modified Mosher's method.
