摘要

New flavone glycoside, genkwanin 4'-O-beta-glucopyranosyl-(1 -> 2)-O-alpha-rhamnopyranoside was isolated from the fronds of new chemotype of Asplenium normale D.Don, together with two known C-glycosylflavones, vicenin-2 and lucenin-2. The chemical structure of the isolated glycoside was established by UV, LC-MS, characterization of acid hydrolysates, and H-1 and C-13 NMR spectroscopy.
