摘要

本文研究了土耳其叶子叶的总酚、总黄酮和花青素含量。此外,还对叶乙醇提取物的抗氧化活性进行了评价,包括ABTS、清除羟基自由基、清除超氧自由基、还原能力和β -胡萝卜素的漂白能力。乙醇提取物的总酚和类黄酮含量分别为468、11±1.53微克/毫克,儿茶素含量为103、05±2.36微克/毫克。随着提取液浓度的增加,花青素含量呈下降趋势(1 mg/mL和2 mg/mL分别为17.92±8.08和13.56±8.22)。在β-胡萝卜素漂白试验中,β-胡萝卜素活性高于BHA(1.540±0.053和1)。还原能力、羟基自由基清除能力和ABTS测试的结果要么非常接近,要么高于所选标准。超氧自由基清除活性低于Trolox作为标准。乙醇提取物的抗氧化活性分别为94.22±0.05958 (ABTS)、78.77±0.84099(羟基自由基清除)和47.86±0.03915(超氧自由基清除)。实验结果表明,乙醇提取物具有一定的药理作用。

Researches on the Epilobium angustifolium L. ethanol extract, Turkey
In this paper, Epilobium angustifolium L. in Turkey was investigated for total phenolics, flavonoids, and anthocyanin amounts. Furthermore, the ethanol extract of the leafs was evaluated for antioxidant activities as ABTS, hydroxyl radical scavenging, superoxide radical scavenging, power of reduction, and bleaching of beta-carotene. The total phenolic and flavonoid contents of the ethanolic extract were found to be 468,11± 1,53 micrograms of pyrocatechol per milligram of the extract and 103,05 ± 2,36 µg catechin per milligram of the extract, respectively. As the extract concentration increased, the amount of anthocyanins showed a decrease (17.92±8.08 and 13.56±8.22 for the 1 mg/mL and 2 mg/mL concentrations, respectively). In the β-carotene bleaching test, higher activity was observed than BHA ( 1.540±0.053 and 1, respectively). The results of the reduction power, hydroxyl radical scavenging, and ABTS tests gave either very close values or higher than the standards chosen. Superoxide radical scavenging activity gave a lower value than the Trolox selected as standard. Antioxidant activity of ethanol extract was found to be 94.22±0.05958 (ABTS), 78.77±0.84099 (hydroxyl radical scavenging) and 47.86±0.03915 (superoxide radical scavenging). The experimental data indicate that Turkey Epilobium angustifolium L. ethanol extract can be used pharmacologically.
