FORMULASI DAN UJI ANTIOKSIDAN ORALLY DISSOLVING FILM EKSTRAK ETANOL BUNGA KECOMBRANG (Etlingera elatior) BERBASIS HPMC DENGAN METODE DPPH
Kecombrang flower (Etlingera elatior) are plant from the Zingiberaceae family which has potential as an antioxidant. Kecombrang flowers have a distinctive smell and sour taste. The orally dissolving film (ODF) formulation which uses a combination of HPMC polymer and maltodextrin was able to eliminate the unpleasant taste of kecombrang flowers. Orally dissolving film (ODF) preparations was made with varying concentrations of kecombrang flower ethanol extract, respectively 125 mg, 150 mg and 175 mg. ODF preparation method in this study utilize use the solvent casting method. The ethanol extract of kecombarang flowers was subjected to a phytochemical screening test, characterization and total flavonoid test. This research aims to determine the best formulation from the results of organoleptic evaluation, film weight, folding resistance, pH of the preparation, disintegration time, percent elongation, film thickness and percentage of moisture loss. The best ODF formula was tested for uniformity of levels and antioxidant test using the DPPH method. The research results showed that kecombrang flowers contain flavonoids, saponins, tannins and terpenoids and a total flavonoid content was obtained with a value of 7.700%. Variations in the concentration of kecombrang flower ethanol extract in the ODF preparation had a significant effect (p
