Abstract

The genus is widely used in traditional folk medicine, but few scientific data exist for this genus. The goal of this study was to characterise the chemical composition and antioxidant activities of leaf extracts using and assays. Six extracts were obtained: hexane (HE), chloroform (CE), ethanol (EE), methanol (ME), water end extract (WEE), and water extract (WE). Thin-layer chromatography (TLC) analysis showed the presence of phenols, saponins, terpenes, and flavonoids. assays demonstrated substantial antioxidant potential, especially for polar extracts (EE, ME, WEE, and WE). Moreover, no toxic effects were observed on mammalian cell lines for most of the extracts at the concentrations evaluated. The nematode was also used as an model for testing antioxidant potential. The EE and WE were chosen, based on previously obtained results. It was observed that neither the EE nor the WE had any toxic effect on development. Additionally, the antioxidant potential was evaluated using -butyl hydroperoxide as a stressor agent. The EE increased the life span of by 28% compared to that of the control, and the WE increased the range to 39.2-41.3%. High-performance liquid chromatography (HPLC-DAD) showed the presence of gallic acid, -coumaric acid, and vitexin in the WE. Therefore, and data demonstrated the antioxidant potential of extracts and their possible biotechnological applications.

摘要

该属植物在传统民间医学中被广泛应用,但针对该属植物的科学数据却很少。本研究的目的是使用 ABTS 和 DPPH 法来表征 叶提取物的化学成分和抗氧化活性。得到了六种提取物:正己烷(HE)、氯仿(CE)、乙醇(EE)、甲醇(ME)、水末端提取物(WEE)和水提取物(WE)。薄层层析(TLC)分析表明存在酚类、皂甙、萜类和类黄酮。ABTS 和 DPPH 法显示出具有很强的抗氧化潜力,特别是极性提取物(EE、ME、WEE 和 WE)。此外,在评估的浓度下,大多数提取物对哺乳动物细胞系没有观察到毒性作用。线虫 也被用作测试抗氧化潜力的 模型。基于之前获得的结果,选择了 EE 和 WE。观察到 EE 和 WE 对 的发育均没有毒性作用。此外,使用 -丁基过氧化物作为应激剂来评估抗氧化潜力。EE 使 的寿命延长了 28%,与对照相比,WE 使寿命延长了 39.2-41.3%。高效液相色谱法(HPLC-DAD)表明 WE 中存在没食子酸、-咖啡酸和牡荆素。因此,ABTS 和 DPPH 数据表明 提取物具有抗氧化潜力,并具有潜在的生物技术应用。
