title: HPLC quantification of kaempferol-3-O-gentiobioside in Cassia alata.
abstract: Kaempferol-3-O-gentiobioside, the major flavonoid glycoside in Indonesian Cassia alata was quantified in various parts of the plant. The mature leaf was found to contain the highest content of this metabolite. A decrease of the flavonoid content in the juvenile leaf during the period of October through December was also observed. The contents ranged from 2.0 to 5.0% and 1.0 to 4.0% in mature and juvenile leaves, respectively. The other parts studied were flower (sepal and petal), rachis, stem and seed. Kaempferol-3-O-gentiobioside was not detected in the seed.
