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)-sop horoside have been isolated together with two known flavonoid glycosides qu ercetin-3-O-sophoroside and quercetin-3,7-O-beta -diglucopyranoside, as wel l as four known triterpenoidal saponins, oleanolic acid-3-O-beta -glucopyra noside, chikusetsusaponin IVa, chikusetsusaponin IVa methyl ester and olean olic acid-3,28-beta -diglucopyranoside. The structures of the isolated comp ounds were verified by means of MS and NMR spectral analyses. (C) 2001 Else vier Science Ltd. All rights reserved.
