Phytochemical Analysis and Antioxidant Activity of Water Hyacinth Flowers (Eichhornia Crassipes) Extract

The purpose of this research was to know about phytochemical compounds and antioxidant activity water hyacinth flowers extract its potential use as a natural antioxidant. Data analysis performed descriptively. Research consisted several stages including sampling, sample preparation, extraction, yield extract, (phenols, tannins, alkaloids, flavonoids saponins), test with DPPH method reducing power. results showed that extracts n-hexane solvent 4.95%, ethyl acetate 1.69%, highest yiled obtained from methanol 26.06%. Results positive for phenolic compounds, saponins. Result interpreted within parameters IC50. IC50 Hyacinth flower were 1085.31 ppm n-hexane, 950.71 35.83 methanol. Small higher activity.
