Description
Summary:This study presents the determination of the total antioxidant capacity (TAC) in twenty edible plants traditionally considered as having pro-health properties and commonly found in East Asia and the Middle East. The aim of the study was to apply a flow-injection amperometric detector (Blizar antioxidant analyzer) for rapid measurement of TAC. Three extraction solvents were used (water, 40% ethanol and 96% ethanol). On average, the edible plants that presented the highest TAC [expressed as gallic acid equivalents (GAE)] for the three extraction solvents were Rosa rugosa (34 mg/g GAE), Scutellaria baicalensis (22.9 mg/g GAE), Forsythia suspensa (11.7 mg/g GAE), Cárthamus tinctórius (11.5 mg/g GAE), Smilacis glabrae rhizoma (10.8 mg/g GAE), Citri reticulatae pericarpium (8.8 mg/g GAE), Apocynum venetum (7.6 mg/g GAE) and Glycyrrhiza uralensis (7.5 mg/g GAE). This investigation contributes to the current knowledge on the overall antioxidant activity of edible plants traditionally consumed for expected pro-health properties, identifying specimens exhibiting high TAC determined by a rapid and low cost amperometric method.
