Fujiwara T, Uehara A, Kitajima J, Iwashina T, Matsumoto S, Watano Y. Genkwanin 4'-O-glucosyl-(1 --> 2)-rhamnoside from new chemotype of Asplenium normale in Japan. Nat Prod Commun. 2014;9(9):1289-90.
New flavone glycoside, genkwanin 4'-O-ß-glucopyranosyl-(1 --> 2)-O-a-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 1H and 13C NMR spectroscopy.
