Antioxidant activity of Loranthus ferrugineus twigs extracts

Background: A coffee parasite, Loranthus ferrugineus, is a type of parasitic plant that widely used as medicinal plant. It has many activities, including an antioxidant agent. Objective: This study to determine the activity in twig extracts L. ferrugineus. Method: The twigs ferrugineus were collected from Pekanbaru, Riau Province, Indonesia. Extraction was carried out by maceration dry using methanol, and then liquid-liquid extraction obtain ethyl acetate methanol fractions. test radical DPPH NO free scavenging methods calculating IC50 values, total phenolic content (TPC) measured. Result: assay method on revealed values 20.85 µg/mL 18.83 µg/mL, respectively. Meanwhile, showed 78.52 greater than 1000 µg/mL. extract 26.78 mgGAE/gram, while it 24.85 mgGAE/gram extract. Conclusion: could inhibit radicals DPPH, which classified very strong sources. inhibition against weak.
