Turkey is the world's leading producer of figs, a typical Mediterranean fruit. The fig, L. (Moraceae), has been widely cultivated since ancient times due to the nutritional value of its fruits. It was aimed to investigate the phytochemical characterization and biological properties of leaf extracts in order to determine their potential for use in the treatment of various diseases. leaves were extracted in 70% methanol at 40 °C under reflux. To obtain extracts of different polarities, the crude extract was fractionated with -hexane, dichloromethane, and -butanol. Phenolic content was determined using liquid chromatography-high resolution mass spectrometry (LC-HRMS). 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and antityrosinase activities of all extracts were investigated using spectrophotometric methods. Furthermore, the DNA-damage protective properties of extracts were investigated using electrophoretic methods. The -butanol extract was found to have the highest total phenolic content, with 72.58 ± 4.52 mg GAE/g dry weight. According to LC-HRMS analysis, rutin (40.13 g/kg) was the most abundant compound in the -butanol extract. The -butanol extract, which was found to have the highest tyrosinase inhibitory effects among the extracts, demonstrated radical scavenging activity of 37.01 ± 1.15% and 82.57 ± 0.88% at 80 and 200 μg/mL, respectively. The -butanol extract had the highest protective effects against Fenton's reagent, UV radiation, and singlet oxygen. Given these findings, it is possible to argue that leaves can be evaluated for developing products that could be used to treat various diseases.
土耳其是世界领先的无花果生产国,无花果是一种典型的地中海水果。无花果,Ficus carica L.(桑科),由于其果实的营养价值,自古以来就被广泛种植。旨在研究无花果叶提取物的植物化学特征和生物学特性,以确定其在治疗各种疾病中的应用潜力。将无花果叶在40℃下于70%甲醇中回流提取。为了获得不同极性的提取物,将粗提取物用正己烷、二氯甲烷和正丁醇进行分级分离。使用液相色谱-高分辨率质谱(LC-HRMS)测定酚类含量。使用分光光度法研究了所有提取物的2,2-二苯基-1-苦基肼(DPPH)自由基清除和抗酪氨酸酶活性。此外,使用电泳方法研究了提取物的DNA损伤保护特性。发现正丁醇提取物的总酚含量最高,为72.58±4.52mg没食子酸当量/g干重。根据LC-HRMS分析,芦丁(40.13g/kg)是正丁醇提取物中含量最丰富的化合物。正丁醇提取物在提取物中具有最高的酪氨酸酶抑制作用,在80和200μg/mL时分别表现出37.01±1.15%和82.57±0.88%的自由基清除活性。正丁醇提取物对芬顿试剂、紫外线辐射和单线态氧具有最高的保护作用。鉴于这些发现,可以认为无花果叶可用于开发治疗各种疾病的产品。
