Jasminum humile (Linn) is highly valued for its medicinal properties. The pulp and decoction made from its leaves are effective for skin diseases. Juice prepared from roots is used against ringworm illness. Our current study aims to illustrate the non-toxicity and protective potential of methanol extract of Jasminum humile (JHM) against CCl-induced oxidative stress in the liver of rats. Qualitative phytochemical screening, total flavonoids (TFC), and total phenolic content (TPC) assays were performed with JHM. The toxicity of the plant was estimated by treating female rats at different JHM doses while to assess anti-inflammatory potential of plant nine groups of male rats (six rats/group) received different treatments such as: CCl only (1 ml/kg mixed with olive oil in a ratio of 3:7), silymarin (200 mg/kg) + CCl, different doses of JHM alone at a ratio of 1:2:4, and JHM (at a ratio of 1:2:4) + CCl, and were examined for different antioxidant enzymes, serum markers, and histological changes, while mRNA expression of stress, inflammatory and fibrosis markers were assessed by real-time polymerase chain reaction analysis. Different phytochemicals were found in JHM. A high amount of total phenolic and flavonoid content was found (89.71 ± 2.79 mg RE/g and 124.77 ± 2.41 mg GAE/g) in the methanolic extract of the plant. Non-toxicity of JHM was revealed even at higher doses of JHM. Normal levels of serum markers in blood serum and antioxidant enzymes in tissue homogenates were found after co-administration of JHM along with CCl. However, CCl treatment caused oxidative stress in the liver by enhancing the levels of stress and inflammatory markers and reducing antioxidant enzyme levels, while JHM treatment showed significant (P < 0.05) downregulation was in mRNA expression of those markers. Investigation of mechanism of specific signaling pathways related to apoptosis and clinical trials to assess safety and efficacy of optimal dosage of Jasminum humile will be helpful to develop FDA-approved drug.
Jasminum humile (Linn) 因其药用特性而备受推崇。其叶子制成的果肉和煎剂可有效治疗皮肤病。从根部提取的汁液可用于治疗癣病。我们目前的研究旨在说明 Jasminum humile(JHM)甲醇提取物对 CCl 诱导的大鼠肝氧化应激的无毒保护潜力。用 JHM 进行了定性植物化学筛选、总黄酮(TFC)和总酚含量(TPC)测定。通过用不同剂量的 JHM 处理雌性大鼠来估计植物的毒性,同时为了评估植物的抗炎潜力,将九组雄性大鼠(每组 6 只)分为不同的处理组:仅 CCl(1ml/kg,与橄榄油以 3:7 的比例混合)、水飞蓟素(200mg/kg)+CCl、JHM 单独的不同剂量(比例为 1:2:4)和 JHM(比例为 1:2:4)+CCl,并检查了不同的抗氧化酶、血清标志物和组织学变化,同时通过实时聚合酶链反应分析评估应激、炎症和纤维化标志物的 mRNA 表达。在 JHM 中发现了不同的植物化学物质。该植物的甲醇提取物中发现了大量的总酚和类黄酮含量(89.71±2.79mgRE/g 和 124.77±2.41mgGAE/g)。即使在较高剂量的 JHM 下,JHM 的毒性也不明显。在 JHM 与 CCl 共同给药后,在血清中的血清标志物和组织匀浆中的抗氧化酶均处于正常水平。然而,CCl 处理通过增强应激和炎症标志物的水平并降低抗氧化酶水平,导致肝脏氧化应激,而 JHM 处理显示这些标志物的 mRNA 表达明显(P<0.05)下调。研究与细胞凋亡相关的特定信号通路的机制,并进行临床试验以评估 Jasminum humile 最佳剂量的安全性和有效性,将有助于开发获得 FDA 批准的药物。
