The determination of total flavonoid content of five Zingiberaceae species was done. The characterization of crude drug, phytochemical screening, and flavonoid isolation was done to the species with the highest total flavonoid content. The crude drug used for flavonoid isolation was distillated for the separation of volatile oil by steam distillation prior to drying and extraction. Isolation of flavonoid was done to the methanolic extract of volatile oil distillation residue and isolate Q was obtained. The crude drug and methanolic extract of distillation residue of Hedychium roxburghii contains flavonoid, steroid/triterpenoid, and quinone. The total flavonoid content of Alpinia sp., Amonnun hoehreutineri, Hornstedtia pininga, tepus, and H. roxburghii are respectively 0,071+0,006, 0,076±0,007, 0,040+0,003. 0,020±0,000, 0,162+0,004%. Isolate Q was identified as a flavonoid aglicone and could be an aurone that has free 4'-OH or flavonol that has free 3-OH with or without free 5-OFT.
