Glycosidic constituents from the roots and rhizomes of Melicope pteleifolia

Abstract

Seven new diglycosidic constituents, named pteleifosides A-G (1-7), along with ten known glycosides, were isolated from the roots and rhizomes of Melicope pteleifolia (Champ. ex Benth.) T. Hartley. The structures of the isolated compounds were established on the basis of chemical and spectroscopic methods, mainly 1D and 2D NMR data and mass spectrometry.
