Immunomodulatory effect and quantitation of a cytotoxic glycosphingolipid from Murdannia loriformis

Abstract

NMR signal reassignments for a cytotoxic glycosphingolipid compound, 2, β-O-D-glucopyranosyl-2-(2′-hydroxy-Z-6′-enecosamide)sphingosine, isolated from an ethanolic extract of the herb Murdannia loriformis, have been achieved by use of FAB-MS, and 1D and 2D 1H and 13C NMR. The amount of 2 in the herb juice was quantitatively determined by use of a validated… (More)
