The antioxidant properties of Glechoma hederacea L. (Lamiaceae), of Serbian origin, were studied in respect to its potential use in foodstuffs. Ethanol-water (8:2, v/v) and purified ethyl acetate extracts of the plant were found to possess significant antioxidant activity. Tests were performed on two different substrates, prime steam pork lard and active-carbon-treated edible sunflower oil, using Schaal oven test storage conditions at 60 degrees C. The ethanol-water and purified ethyl acetate extracts of G. hederacea showed strong concentration-dependent antioxidant activity. On the contrary, under the Rancimat method conditions at 120 degrees C, the ethanol-water extract showed significantly stronger antioxidant activity, in comparison with the other tested extracts. All activities were compared with commercial antioxidants, such as BHA and a tocopherol mixture, respectively. For the first time, the activity of the flavonol quercetagetin was determined.
对原产于塞尔维亚的唇形科植物连钱草（Glechoma hederacea L.）在食品中的潜在用途进行了抗氧化性能研究。发现该植物的乙醇 - 水（8:2，v/v）提取物和纯化乙酸乙酯提取物具有显著的抗氧化活性。在两种不同的底物上进行了测试，即优质蒸汽猪脂和活性炭处理的食用向日葵油，采用Schaal烘箱试验在60℃的储存条件。连钱草的乙醇 - 水提取物和纯化乙酸乙酯提取物表现出很强的浓度依赖性抗氧化活性。相反，在120℃的Rancimat法条件下，与其他测试提取物相比，乙醇 - 水提取物表现出显著更强的抗氧化活性。所有活性均分别与商业抗氧化剂如丁基羟基茴香醚（BHA）和生育酚混合物进行了比较。首次测定了黄酮醇槲皮万寿菊素的活性。
