Antioxidant Potential of Carissa carandas Seed Comparing to The Dietary Supplement Products

Abstract

Carissa carandas is well known for its various medicinal properties for example, it can be used to treat the liver dysfunction, break fever and to counteract the putrefaction of blood. The purposes of this study were to analyze the antioxidant capacity, which included total phenolic content, ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, total anthocyanin content, proanthocyanins,  ascorbic acid content and tyrosinase inhibitory activities determination comparing to dietary supplement products. A seed of C.carandas showed the highest value of total phenolic content, FRAP, DPPH and proanthocyanidins that were 256.42 mgGAE/g, 2104.31 µmolFeSO₄/g, 285.06 mgAAE/g and 465.69 mgCE/g, respectively. Cranberry extract was found to have higher rate of tyrosinase inhibition (27.74 mgKAE/g) than other samples. In this study, the bilberry extract showed the highest amount of total anthocyanins with 130.60 mg/L(cyanidin-3-glucoside), and contained the greatest amount of vitamin c with 123.93 mg/g. This study revealed that C. carandas seeds were rich in natural antioxidant. Our discovery suggested that the extract from C. carandas seeds have good commercial potential as a promising antioxidant for using in dietary supplement food as well as cosmetics.
