The present study investigated the antifungal activity and mode of action of four leaf extracts, essential oil (EO), and EO against . was detected with the internal transcribed spacer (ITS) region. The chemical compositions of chloroform and dichloromethane extracts of leaves and EO were analyzed using GC-MS analysis. In addition, a molecular docking analysis was used to identify the expected ligands of these extracts against eleven proteins. The nucleotide sequence of the Lactucae isolate was deposited in GenBank with Accession No. MT249304.1. The EO, chloroform, dichloromethane and ethanol efficiently inhibited the growth at concentrations of 75.5 and 37.75 mg/mL, whereas ethyl acetate, and EO did not exhibit antifungal activity. The GC-MS analysis revealed that the major and most vital compounds of the EO, chloroform, and dichloromethane were thymol, carvacrol, tetratriacontane, and palmitic acid. Moreover, molecular modeling revealed the activity of these compounds against . Chloroform, dichloromethane and ethanol, olive leaf extract, and EO showed a strong effect against . Consequently, this represents an appropriate natural source of biological compounds for use in healthcare. In addition, homology modeling and docking analysis are the best analyses for clarifying the mechanisms of antifungal activity.
本研究调查了四种叶提取物、精油(EO)和 EO 的抗真菌活性和作用模式,使用内部转录间隔区(ITS)区域检测 。使用 GC-MS 分析分析了氯仿和二氯甲烷提取物和 EO 的化学成分。此外,还使用分子对接分析鉴定了这些提取物对 11 种 蛋白的预期配体。从 Lactucae 分离株获得的核苷酸序列已在 GenBank 中以登录号 MT249304.1 进行了存储。EO、氯仿、二氯甲烷和乙醇在 75.5 和 37.75 mg/mL 的浓度下有效地抑制了生长,而乙酸乙酯和 EO 则没有表现出抗真菌活性。GC-MS 分析表明,EO、氯仿和二氯甲烷的主要和最重要的化合物是百里酚、香芹酚、三十烷和棕榈酸。此外,分子建模显示这些化合物对 的活性。氯仿、二氯甲烷和乙醇、橄榄叶提取物和 EO 对 表现出强烈的抑制作用。因此,这是一种用于医疗保健的生物化合物的合适天然来源。此外,同源建模和对接分析是阐明抗真菌活性机制的最佳分析方法。
