The chemical profiles of both () aerial parts and roots extracts were evaluated with LC-ESI-TOF-MS/MS analysis. Twenty-four compounds were detected. Among them, some are detected in both the aerial parts and the roots extracts, and others were detected in the aerial parts only. The detected compounds were mainly flavonoids, phenolic compounds, triterpenes and other miscellaneous compounds. Such compounds contribute to the diverse pharmacological activities elicited by the species. This study aimed to elucidate the antiepileptic effect of aerial parts and roots crude extracts against pentylenetetrazole (PTZ)-induced kindling in mice. Male albino mice were divided into four groups, eight animals each. All groups, except the control group, were kindled with PTZ (35 mg/kg i.p.), once every alternate day for a total of 15 injections. One group was left untreated (PTZ group). The remaining two groups were treated prior to PTZ injection with either aerial parts or roots crude extract (400 mg/kg, orally). Pretreatment with either extract significantly reduced the seizure scores, partially reversed the histological changes in the cerebral cortex and exerted antioxidant/anti-inflammatory efficacy evinced by elevated hippocampal total antioxidant capacity and SOD and catalase activities, parallel to the decrement in MDA content, iNOS activity and the TXNIB/NLRP3 axis with a subsequent decrease in caspase 1 activation and a release of IL-1β and IL-18. Moreover, both extracts suppressed neuronal apoptosis via upregulating Bcl-2 expression and downregulating that of Bax, indicating their neuroprotective and antiepileptic potential. Importantly, the aerial parts extract elicited much more antiepileptic potential than the roots extract did.
采用液相色谱-电喷雾电离-飞行时间串联质谱(LC-ESI-TOF-MS/MS)分析对()地上部分和根提取物的化学特征进行了评估。共检测到24种化合物。其中,有些化合物在地上部分和根提取物中均有检测到,而其他一些化合物仅在地上部分被检测到。所检测到的化合物主要为黄酮类、酚类化合物、三萜类和其他杂类化合物。这些化合物促成了该物种所引发的多种药理活性。本研究旨在阐明()地上部分和根粗提取物对戊四氮(PTZ)诱导的小鼠点燃模型的抗癫痫作用。将雄性白化小鼠分为四组,每组8只动物。除对照组外,所有组均腹腔注射PTZ(35 mg/kg)进行点燃,每隔一天注射一次,共注射15次。一组不进行处理(PTZ组)。其余两组在注射PTZ前分别口服()地上部分或根粗提取物(400 mg/kg)进行处理。用任一提取物进行预处理均显著降低了癫痫发作评分,部分逆转了大脑皮质的组织学变化,并发挥了抗氧化/抗炎功效,表现为海马总抗氧化能力、超氧化物歧化酶(SOD)和过氧化氢酶活性升高,同时丙二醛(MDA)含量、诱导型一氧化氮合酶(iNOS)活性以及TXNIB/NLRP3轴下降,随后半胱天冬酶1激活减少以及白细胞介素-1β(IL-1β)和白细胞介素-18(IL-18)释放减少。此外,两种()提取物均通过上调Bcl-2表达和下调Bax表达来抑制神经元凋亡,表明它们具有神经保护和抗癫痫潜力。重要的是,地上部分提取物的抗癫痫潜力比根提取物更强。
