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.

用安培法测定东亚和中东地区常见的食用植物的总抗氧化能力

这项研究提出了二十种可食用植物中总抗氧化能力（TAC）的测定方法，这些植物通常被认为具有促进健康的特性，并且在东亚和中东很常见。该研究的目的是应用流动注射安培检测器（Blizar抗氧化剂分析仪）来快速测量TAC。使用了三种萃取溶剂（水，40％乙醇和96％乙醇）。平均而言，三种提取溶剂的TAC最高[以没食子酸当量（GAE）表示]的可食植物为：皱叶蔷薇（34 mg / g GAE），黄cut（22.9 mg / g GAE），连翘（Forsythia suspensa（ 11.7 mg / g GAE），金缕梅（11.5 mg / g GAE），S草（Smilacis glabrae rhizoma）（10.8 mg / g GAE），网状柠檬皮（8.8 mg / g GAE），罗布麻（7.6 mg / g GAE）和甘草（7.5 mg / g GAE）。这项研究有助于了解有关传统食用的可食用植物的总体抗氧化活性，以期获得预期的有益健康的特性，从而鉴定出通过快速低成本安培法测定的高TAC的标本。
