- Novelina, Tuty Anggraini, Rudi Hermansyah

Abstract

Chlorophyll is known to be used as a natural dye. The last few years it is known that chlorophyll has an important role as a source of antioxidants that are good for health. The availability of sources of chlorophyll in Indonesia is very large, one of which is the green grass jelly leaves (Premna obliongifolia Merr). The research objective is to get grass jelly leaf extract as a source of chlorophyll and know the characteristics of the resulting extract chlorophyll. The process of extraction is done by maceration with ethanol and addition of 7% NaHCO3. The yield of the concentrated extract obtained was 35% -36%. Concentrated extract of leaves of grass jelly contains the highest levels of total chlorophyll 1184.475 mg / L. The antioxidant activity of IC 50 (ppm) is 6533.9. Likewise, the results of toxicity tests is known that chlorophyll extract treatment response inactive with LC50> 1000 mg / mL is 1170.5 to 1504.8 mg / mL.
