Abstract


The research about flavonoid compound isolation and compound identification of etanol extract from pacing rhizome of Costus Speciosus (J.Koenig) Sm. Isolation stage includes extraction with maserasi method (95%) with extract-bath 8,4% results in thick extract as many as 135 gram, fracsination using liquid-liquid extract method, using n-heksan solvent, acetate ethyl, and water. Subfracsination is done on acetate ethyl fraction with using preparative KLT. Isolate identification done using UV-Visible spectrophotometry with gestalt reagent. Based on isolate characterization, it can be concluded that isolate is flavonoid compound from flavonol category.

Keywords


Pacing rhizome, Flavonoid, UV-visible spektrophotometry, gestalt raegent.
