title: Chemical constituents of Pyrrosia petiolosa.
abstract: The new flavone diglycoside 7-O-[6-O-(alpha-L-arabifuranosyl)-beta-D-glucopyranosyl]-gossypetin, named as pyrropetioside, along with 13 known compounds (including 3 artifacts) have been isolated from Pyrrosia petiolosa. Their structures have been elucidated by means of chemical and spectroscopic methods including IR, MS, 1D and 2D NMR techniques.
