Acylated flavonoid glycosides from Bassia muricata

From the arial parts of Bassia muricata, two acylated flavonoid glycosides quercetin-3-O-(6′-caffeoyl)-sophoroside and quercetin-3-O-(6′-feruloyl)-sophoroside have been isolated together with two known flavonoid glycosides quercetin-3-O-sophoroside and quercetin-3,7-O-β-diglucopyranoside, as well as four known triterpenoidal saponins, oleanolic acid-3-O-β-glucopyranoside, chikusetsusaponin IVa, chikusetsusaponin IVa methyl ester and oleanolic acid-3,28-β-diglucopyranoside. The structures of the isolated compounds were verified by means of MS and NMR spectral analyses. © 2001 Elsevier Science Ltd. All rights reserved.
