摘要

背景:胡茉莉是木犀科传统药用植物之一。它在阿富汗、巴基斯坦、尼泊尔、缅甸、喜马拉雅山和中国西南部随处可见。茶叶和树皮通常用于治疗各种疾病,如中枢神经系统疾病、抗炎症和防腐剂。目的:研究胡麻叶甲醇提取物(MEJHL)的抗焦虑作用。材料和方法:采用Elevated Plus Maze(EPM)和光/暗探索模型评价胡麻叶提取物的解焦虑活性。使用Rota-Rod装置、动力计和氯胺酮诱导的睡眠时间分别观察运动协调和镇静效果。大脑神经递质如GABA水平通过验证的方法估计。结果:从急性毒性研究中发现,胡麻叶提取物是无毒的。在所有提取物中,只有甲醇提取物表现出显著的抗焦虑活性(P<0.05)。初步的植物化学筛选揭示了MEJHL中存在碳水化合物、黄酮类化合物和生物碱。抗焦虑模型的结果清楚地表明,200mg/kg剂量的MEJHL分别显著增加了进入EPM和亮/暗模型的开放臂和亮区的次数和平均时间(P<0.05)。在运动协调活动的情况下,与对照组相比,MEJHL对Rota棒脱落的潜伏期没有任何显著影响(在任何剂量下)。此外,在动作光度计和氯胺酮诱导的睡眠潜伏期和总睡眠时间方面没有观察到显著的影响。整个大脑和小脑的神经递质估计结果显示,GABA浓度的增加与标准药物地西泮相似。结论:该植物甲醇提取物中存在生物碱,可作为一种潜在的天然抗焦虑药物来源,镇静效果较差。

Methanolic extract of Jasminum humile L. leaves possess anxiolytic activity mediated via the gabaergic system in the central nervous system of mice
Background: Jasminum humile L. is one of the traditional medicinal plants from Oleaceae family. It is abundantly available in Afghanistan, Pakistan, Nepal, Burma, the Himalayas, and southwest China. The tea of leaves and barks are used conventionally in the treatment of various diseases such as central nervous system disorder, anti-inflammatory, and antiseptic. Aim: The present study was undertaken to investigate the anxiolytic effect of methanolic extract of J. humile L. leaves (MEJHL). Materials and Methods: Anxiolytic activity of J. humile L. leaves extracts were evaluated using Elevated Plus-Maze (EPM) and light/dark exploration models. The motor coordination and sedative effect were also observed using Rota Rod apparatus, actophotometer, and ketamine-induced sleeping time, respectively. Brain neurotransmitters like GABA level were estimated by validated methods. Results: From the acute toxicity studies, extracts of J. humile L. leaves were found to be nontoxic. Among all extracts, the only methanolic extract showed significant (P < 0.05) anxiolytic activity. Preliminary phytochemical screening revealed the presence of carbohydrates, flavonoids, and alkaloids in the MEJHL. The results of anxiolytic models clearly depicted that MEJHL at the dose of 200 mg/kg significantly (P < 0.05) increased the number of entries and the average time spent in the open arms and light compartment of the EPM and light/dark models, respectively. In the case of motor coordination activity, the MEJHL does not cause any significant effect (at any dose) on the latency to fall off from the Rota Rod bar compared to the control group. Moreover, no remarkable effects in actophotometer and on ketamine-induced sleep latency and total sleeping time induced by ketamine was observed. Results of neurotransmitter estimation in the whole brain and the cerebellum revealed the increased concentration of GABA was similar to standard drug diazepam. Conclusions: The presence of alkaloids in the methanolic extract of this plant can serve as a potential resource for natural psychotherapeutic agents against anxiety with less sedation.
