title: A new flavone glycoside from the fern Pteris cretica.
abstract: A new flavone glycoside isolated from the fern Pteris cretica has been shown to be luteolin 7-O-robinobioside (1) by chemical and spectral methods. In addition luteolin 7-O-rutinoside (2) and luteolin 7-O-glucoside (3) have been isolated from this plant. Flavonoid 2 is reported for the first time in ferns.
