The potential of Dendrophthoe pentandra and Scurrula ferruginea stem from Syzygium aqueum as source of natural antioxidant

Abstract

Many studies show the antioxidant ability of the parasite plant. This study aims to determine the capacity of Dendrophthoe pentandra (L.) Miq and Scurrula ferruginea stem from Syzygium aqueum to use as a natural antioxidant source. The sample was taken from the host Syzygium aquarium. The samples were extracted with ethanol using maceration. The parameters were determined spectrophotometrically using specific reagents that were antioxidant capacity using 1,1-diphenyl-2-picrylhydrazyl, phenolics compounds using Folin-Ciocalteu, flavonoids using AlCl3, ascorbic acid using sulfosalicylic acid, while chlorophyll and carotenoid using dimethyl sulfoxide. The result of D. pentandra (L.) Miq and S. ferruginea extract showed that IC50 were 15.09±1.02 and 20.53±1.77 mg/ml, the content of phenolics compounds were 557.45±19.77 and 433.99±20.89 mg GAE/ml extract, flavonoids were 9.72±0.23 and 3.02±0.71 mg QE/ml extract, chlorophylls-a were 2.67± 0.15 and 2.77±0,08 mg/g extract, chlorophylls-b were 3.34±0.06 and 3.44±0.04 mg/g extract, total chlorophylls were 6.01±0.21 mg/g extract, carotenoids were 1.71±0.01 and 2.10±0.01 mg/g extract respectively. The stems of both D. pentandra (L.) Miq and S. ferruginea from Syzygium aquarium has very strong antioxidant abilities so they are the potential to use as a source of natural antioxidants. The compounds that support the antioxidant activity were phenolic, flavonoids, and ascorbic acids. The results of this study will open up opportunities to obtain new sources of antioxidants that can be utilized in human health management.
