Abstract

Pro-inflammatory enzymes play a key role in inflammatory processes and are potential targets of anti-inflammatory drugs. In this study, the objective was to evaluate the antiradical activity of the extracts and their ability to inhibit phospholipase A and 15-lipoxygenase activity. The hydroethanolic extract of revealed the strongest reducing power with an IC of 7.29 ± 0.61 µg/mL. The three most active extracts on PLA were hydroethanolic extracts of (IC of 21.43 ± 0.66 μg/mL), (IC of 23.72 ± 0.71 µg/mL), (IC of 24.49 ± 0.39 µg/mL). The best inhibitory activity on 15-lipoxigenase was obtained with aqueous and hydroethanolic extracts of with IC of 18.35 ± 1.26; 18.47 ± 1.12 µg/mL respectively. The present study showed that extracts of leaves of and roots of have antioxidant activity and effectively inhibit sPLA, and 15-LOX pro-inflammatory enzymes

8种马里传统治疗炎性疾病的药用植物抗自由基活性、磷脂酶A和15-脂氧合酶抑制活性研究
促炎酶在炎症过程中起关键作用,是抗炎药物的潜在靶点。在本研究中,目的是评估提取物的抗自由基活性及其抑制磷脂酶A和15-脂氧合酶活性的能力。其中,水乙醇提取物还原力最强,IC为7.29±0.61µg/mL。聚乳酸活性最强的3种提取物分别为氢乙醇提取物(IC为21.43±0.66 μg/mL)、(IC为23.72±0.71 μg/mL)、(IC为24.49±0.39 μg/mL)。以IC为18.35±1.26的水提液和乙醇提液对15-脂氧化酶的抑制活性最好;18.47±1.12µg/mL。本研究表明,其叶提取物和根提取物具有抗氧化活性,能有效抑制sPLA和15-LOX促炎酶
