title: Isolation and characterization of an antiviral flavonoid from Waldsteinia fragarioides.
abstract: The antiviral agent in a fraction from Waldsteinia fragarioides (Rosaceae) was purified using bioassay-guided fractionation of activity against herpes simplex type 1 virus. Structural eluciation by instrumental methods identified the active component to be the known flavonoid glycoside, isoquercitrin (3,3',4',5,7-pentahydroxyflavone-3 beta-O-glucoside), which had not previously been shown to possess antiviral activity.
