IDENTIFIKASI SENYAWA FLAVONOID PADA FRAKSI N-BUTANOL BUNGA BUGENVIL UNGU (Bougenvillea spectabilis) DENGAN SPEKTROFOTOMETER UV-VIS

Bougainvillea purple flowers (bougenvillea spectabilis) is a plant that contains secondary metabolites one of them flavonoids. This study aims to identify the type flavonoids in bougenville blend n-butanol. The identification bougainvillea n-butanol fraction was performed by separation method using preparative TLC eluent nbutanol: acetic acid: water (4: 1: 5) 3 stains with Rf 0.2, 0.3, and 0, 6 shear reagent at 0.2 flavonoid guessing UV-Vis spectrophotometry, based on analysis spectrophotometer has absorption wavelength 372 band 1 276 2 then are expected. results this showed contain Conclusion From Based thin layer chromatography spectrum compound reagents flower thought flavonoids.
