Dietary medicinal herbs (DMHs) are superior reservoirs for natural antioxidants and safe for long-term consumption. Chinese government recently announced an official list of traditional Chinese DMHs to support civil health promotion. However, antioxidative capacity (AOC) and total phenol contents (TPC) of these listed herbs were not comprehensively and systematically evaluated. In this study, AOC of 94 listed DMHs in water extract were investigated by three techniques including radical scavenging and ferric reducing antioxidative power. The results showed that emblic leafflower, rose, and clove possessed the highest AOC, while TPC was significantly correlated with AOC. While traditional Chinese medicines are categorized by the nature of Yin-Yang, this study demonstrated that Yin DMHs are statistically correlated with high AOC. In this study, AOC and TPC of 94 traditional Chinese DMHs were documented systematically. Emblic leafflower, rose and clove were shown to possess the highest AOC. TPC in traditional Chinese DMHs was significantly correlated with the AOC, while DMHs with Yin characteristic might be used as an indicator to identify potential antioxidative herbs.
食用药用植物是天然抗氧化剂的优质来源，且长期食用安全。中国政府最近公布了一份官方的中国传统食用药用植物清单，以支持全民健康促进。然而，这些列入清单的草药的抗氧化能力（AOC）和总酚含量（TPC）尚未得到全面系统的评估。在本研究中，通过自由基清除和铁还原抗氧化能力等三种技术，对94种列入清单的食用药用植物水提取物的AOC进行了研究。结果表明，余甘子、玫瑰和丁香具有最高的AOC，而TPC与AOC显著相关。虽然传统中药按阴阳属性分类，但本研究表明，阴性食用药用植物在统计学上与高AOC相关。在本研究中，系统记录了94种传统中药的AOC和TPC。余甘子、玫瑰和丁香被证明具有最高的AOC。传统中药中的TPC与AOC显著相关，而具有阴性特征的食用药用植物可能作为识别潜在抗氧化草药的指标。
