ISOLASI FLAVONOID DARI EKSTRAK METANOL Drymaria cordata Willd SEBAGAI BAHAN PEMBELAJARAN FITOKIMIA
Abstract: Due to develop the
potention of Drymaria cordataWilld. as a medicine from natural product, an
experiment was done to isolatethe flavonoid from this plant. Flavonoid isolated
by extraction with methanol,followed with fractionation using ethyl acetat and
ethanol. Examination ofethanol fraction by thin layer chromatography with
stationary phase silica gelGF 254 and mobile phase 15 % acetic acid showed
phenolic compound ondetection with FeCl3 and gave yellow colour with amonia
thatidentify flavonoid compound. Purification has done using column
chromatographyand paper chromatography.
The structureof two isolated compounds was identified by ultraviolet
spectrophotometry. Thisexperiment can be used as laboratory practice or studied
material onPhytochemistry.
