Abstract

, a flowering plant from the Malvaceae family traditionally used to treat ailments such as boils and scabies, is here investigated for its potential health benefits. The study focused on evaluating its antioxidant and antidiabetic properties , as well as the anxiolytic and antidepressant activities of the methanol extract of leaf (MEBP). The study employed various assays to evaluate antioxidant activity, including 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, reducing power capacity, and quantification of the total phenolic and flavonoid contents of MEBP. Additionally, anxiolytic and antidepressant activities were evaluated through four tests: elevated plus-maze test (EPMT), light-dark box test (LDBT), forced swimming test (FST), and tail suspension test (TST). Antidiabetic effect was determined using α-amylase inhibition assay. Docking analysis was performed using BIOVIA and Schrödinger Maestro (v11.1), and the absorption, distribution, metabolism, and excretion/toxicity (ADME/T) properties of bioactive substances were investigated using a web-based technique. MEBP exhibited moderate antioxidant activity in DPPH radical scavenging and reducing power capacity assays, with a dose-dependent response. The total phenolic and flavonoid contents measured were 70 ± 1.53 mg and 22.33 ± 1.20 mg, respectively. MEBP demonstrated significant effects in α-amylase inhibition comparable to acarbose. In behavioral tests, MEBP dose-dependently altered time spent in open arms/light box and closed arms/dark box, indicating anxiolytic effects. Moreover, MEBP significantly reduced immobility duration in FST and TST, suggesting antidepressant properties. Molecular docking analysis revealed favorable interactions between beta-sitosterol and specific targets, suggesting the potential mediation of anxiolytic and antidiabetic effects. Overall, MEBP exhibits notable anxiolytic and antidepressant properties, along with moderate antioxidant and antidiabetic activities.

摘要

锦葵科的一种开花植物,传统上用于治疗疖子和疥疮等疾病,本文对其潜在的健康益处进行了研究。该研究重点评估了其抗氧化和抗糖尿病特性,以及锦葵叶甲醇提取物(MEBP)的抗焦虑和抗抑郁活性。该研究采用了各种测定方法来评估抗氧化活性,包括2,2-二苯基-1-苦基肼(DPPH)自由基清除、还原能力以及MEBP中总酚和黄酮含量的定量。此外,通过四项测试评估抗焦虑和抗抑郁活性:高架十字迷宫试验(EPMT)、明暗箱试验(LDBT)、强迫游泳试验(FST)和悬尾试验(TST)。使用α-淀粉酶抑制试验测定抗糖尿病作用。使用BIOVIA和薛定谔大师(v11.1)进行对接分析,并使用基于网络的技术研究生物活性物质的吸收、分布、代谢和排泄/毒性(ADME/T)特性。MEBP在DPPH自由基清除和还原能力测定中表现出中等抗氧化活性,呈剂量依赖性反应。测得的总酚和黄酮含量分别为70±1.53毫克和22.33±1.20毫克。MEBP在α-淀粉酶抑制方面表现出与阿卡波糖相当的显著效果。在行为测试中,MEBP剂量依赖性地改变了在开放臂/亮箱和封闭臂/暗箱中花费的时间,表明具有抗焦虑作用。此外,MEBP显著缩短了FST和TST中的不动时间,表明具有抗抑郁特性。分子对接分析揭示了β-谷甾醇与特定靶点之间的良好相互作用,表明其可能介导抗焦虑和抗糖尿病作用。总体而言,MEBP表现出显著的抗焦虑和抗抑郁特性,以及中等的抗氧化和抗糖尿病活性。
