title: Urakunoside, a new tetraglycosyl kaempferol from petals of the Wabisuke camellia cv. Tarokaja.
abstract: A new tetraglycosyl flavonol, 3-O-[2-O-xylosyl-6-O-(3-O-glucosyl-rhamnosyl) glucosyl] kaempferol was isolated from pale purplish-pink petals of Wabisuke camellia cv. Tarokaja with three known flavonols. It was named urakunoside after the species name of Tarokaja, Camellia uraku. Urakunoside was a major flavonol component in the Tarokaja petals, but was not detected in petals of Tarokaja's presumed ancestor species.
