L. is of great interest as a traditional additive in various folk remedies in several countries, including Turkey. We aimed to determine the chemical profile (assisted by high-Performance liquid chromatography-electrospray ionization-tandem mass apectrometry (HPLC-ESI-MS/MS) experiments of three extracts obtained by different polarity solvents viz. ethyl acetate (to extract semipolar compounds), methanol and water (to extract highly polar metabolites) from leaves. Their anti-diabetic effects were investigated by assessing their inhibition toα-amylase and α-glucosidase. Assessment of the neuroprotective potential of the three extracts was carried out against acetyl-(AChE) and butyryl-(BChE) cholinesterase enzymes. HPLC-ESI-MS/MS experiments showed a total of 17 chromatographic peaks primarily classified to six flavonoids, two saponins, and six fatty acids. Antioxidant assays revealed remarkable activity for the ethyl acetate and methanol extracts. The BChE inhibition was considerably more significant (4.08 mg galantamine equivalent (GALAE)/g) for the ethyl acetate extract, whereas the methanol extract had good inhibitory efficacy for AChE (2.05 mg GALAE/g). Through network pharmacology, the compounds' mechanism of action of targeted key gene in their associated diseases were identified. The hubb gene signal transducer and activator of transcription 3 (STAT3) and tumour necrosis factor (TNFα) where the site of action in inflammation bowel disease. The results offer possibilities for the prospective application of in metabolic regulation, blood glucose control, and as a source of bioactive compounds with cholinesterase enzyme inhibitory characteristics which could be of relevance in the cosmetic or pharmaceutical industry for combating melanogenesis.
在包括土耳其在内的几个国家,作为各种民间疗法中的传统添加剂,L.具有极大的研究价值。我们旨在通过高效液相色谱 - 电喷雾电离 - 串联质谱(HPLC - ESI - MS/MS)实验确定从叶片中用不同极性溶剂(即乙酸乙酯(用于提取半极性化合物)、甲醇和水(用于提取高极性代谢物))获得的三种提取物的化学概况。通过评估它们对α - 淀粉酶和α - 葡萄糖苷酶的抑制作用来研究它们的抗糖尿病作用。对这三种提取物的神经保护潜力进行了针对乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)的评估。HPLC - ESI - MS/MS实验显示共有17个色谱峰,主要分为六种黄酮类化合物、两种皂苷和六种脂肪酸。抗氧化试验表明乙酸乙酯和甲醇提取物具有显著活性。乙酸乙酯提取物对BChE的抑制作用更为显著(4.08毫克加兰他敏当量(GALAE)/克),而甲醇提取物对AChE具有良好的抑制效果(2.05毫克GALAE/克)。通过网络药理学,确定了这些化合物在其相关疾病中靶向关键基因的作用机制。关键基因信号转导和转录激活因子3(STAT3)和肿瘤坏死因子(TNFα)是炎症性肠病的作用位点。这些结果为L.在代谢调节、血糖控制方面的潜在应用提供了可能性,并且作为具有胆碱酯酶抑制特性的生物活性化合物来源,可能在化妆品或制药行业对抗黑色素生成方面具有相关性。
