Two New Flavonoid Glycosides from Viscum album ssp. album

摘要

Two new flavonoid glycosides, 5,7-dimethoxy-flavanone-4'-0-[2"-0-(5"'-0-trans-cinnamoyl)-beta-D-apiofuranosyl]-(3-D-glucopyranoside (1) and 2'-hydroxy-4',6'-dimethoxy-chalcone-4-0-[2"-0-(5"'-0-trans-cinnamoyl)-bet-D-apiofuranosyl]-beta-D-glucopyranoside (2), were isolated from Viscum album L. ssp. album, in addition to six known compounds: syringin, coniferin, kalopanaxin D, 2'-hydroxy-4',6'-dimethoxy-chalcone-4-0-beta-D-glucopyra-noside,5,7-dimethoxy-flavanone-4'-0-beta-D-giucopyranoside, 5,7-dimethoxy-flavanone-4'-0-[beta-D-apiofuranosyl(l->2)]-p-D-glucopyranoside. Their structures were elucidated by spectroscopic (UV, IR, NMR and MS) methods.
