Sulfated Lupane Triterpene Derivatives and a Flavone C-Glycoside from Gypsophila repens

Abstract

A new sulfated lupane triterpene, Gypsophilin (1), and its glucosyl ester, Gypsophilinoside (2) were isolated from the roots of Gypsophila repens whereas a new flavone C-glycoside (3) was obtained from the aerial parts. Their structures were established as (3β)-3-O-(sulfo)lup-20(29)-en-23,28-dioic acid (1), (3β)-3-O-(sulfo)lup-20(29)-en-23,28-dioic acid -28-O-β-D-glucopyranosyl ester (2) and luteolin-7-O-α-L-arabinopyranosyl-6-C-β-glucopyranoside (3) by spectroscopic methods such as 1D and 2D NMR, HR-ESI-MS and FAB-MS.
