Isi artikelHerbs of Taraxacum officinale, a native of Europe, contain a flavonoid, steroid/triterpenoid, saponin, tanin, and a volatile oil. The purpose of this research was to determine the flavonoid substances, after partitioning of the methanolic extract by the Charaux-Paris methods with n-butanol. Identification by uv-visible spectrophotometry confirmed that flavonoid from isolate Ia was a flavonol with an OH at 3, 7 psition, oxygen at 6 or 8, while isolate III, also a flavonol, showed an OH at 3, 7 position, oxygen at 6 or 8, and besides that an additional 0-diOH attached to ring B.
