A New Oleanane Type Saponin from the Aerial Parts of Elaeocarpus hainanensis

Elaeocarpus hainanensis has been used in the Oriental medicine but there are very few studies on its phytochemical profile. Our ongoing research on chemical constituents from Elaeocarpus plants in Vietnam led to the isolation of a new oleanane-type saponin from the aerial part of E. hainanensis. Its...

Zusammenfassung:Elaeocarpus hainanensis has been used in the Oriental medicine but there are very few studies on its phytochemical profile. Our ongoing research on chemical constituents from Elaeocarpus plants in Vietnam led to the isolation of a new oleanane-type saponin from the aerial part of E. hainanensis. Its structure was identified as 1 alpha-hydroxy-olean-11-oxo-12-en-3-O-beta-L-arabinopyranoside (1) on the basis of extensive chemical and spectroscopic analyses including NMR and MS spectra. The occurence of the unique oleanane-type saponins in E. hainanensis contributed to impact phytochemical profile associated with chemotaxanomy meaning of the title plant.
