Three new lignan glycosides from<i>Mananthes patentiflora</i>

Abstract

Abstract Three new lignan glycosides, mananthosides I–K (1–3), were isolated from the ethanolic extract of the aerial part of Mananthes patentiflora. The structure elucidation of these compounds was mainly established on the basis of 1D NMR, 2D NMR and HR-MS spectroscopic analysis.
