Solvent concentration effect on antioxidant activity and total phenolic content of Malaysian herbs
description Generally, herbal plants that are relatively abundant sources of antioxidant compounds with high antioxidant activities have been consume for thousands of century by world population (Amin et al., 2004, 2006; Amin & Lee, 2005). The objective of this research was to determine total phenolic content, antioxidant activities of Malaysian herbal plants. The potential of using herbal Pandanus amaryllifolius (PA), Sauropus androgynous (SA) and Persicaria odorata (PO) as a natural antioxidant for food applications were investigated. Total phenolic content (TPC) of herbs was determined using Folin-Ciocalteau reagent assay and antioxidant activity were analyzed by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The determination of TPC and antioxidant activity was done for each plant extract by using ethanol as solvent, different concentration of ethanol aqueous solutions, including 95%, 75%, 50%, 25% and 0%.
