Clinacanthus nutans:a review of the medicinal uses,pharmacology and phytochemistry

Clinacanthus nutans Lindau is known as snake grass belonging to the Acanlhaceae family.This plant has diverse and potential medicinal uses in traditional herbal medicine for treating skin rashes,insects and snake bites,lesions caused by herpes simplex virus,diabetes,and gout in Malaysia.Indonesia.Thailand and China.Phylochemieal investigations documented the varied contents of bioaclive compounds from litis plant namely flavonoids,glycosides,glycoglyeerolipids.cerebrosides and monoacylmonogalatosylglycerol.The pharmacological experiment proved that various types of extracts and pure compounds from this species exhibited a broad range of biological properties such as anti-inflammatory,antiviral,antioxidant,and anti-diabetic activities.The lindings of toxicity study showed that extracts from this plant did not show any toxicity thus it can be used as strong therapeutic agents for specific diseased conditions.However,further experiments on chemical components and their mode of action showing biological activities are required to elucidate the complete phytochemical profile and assess to confirm their suitability tor future drugs.This review summarizes the medicinal uses,phytochemistry and pharmacology of this plant in order to explore its therapeutic potential and gaps necessitating for prospected research work.

姜黄素对氯化锂-匹罗卡品诱导癫癎持续状态的预防作用

目的探讨姜黄素对氯化锂-匹罗卡品诱导大鼠癫持续状态(SE)的预防作用及其神经元保护作用。方法Spra-gue-Daw ley(SD)大鼠45只随机均分成3组:预防组(n=15)、非预防组(n=15)和对照组(n=15)。观察各组SE的发生情况;SE后24 h,用焦油紫尼氏染色检查海马CA3区的存活神经元,用DNA片段原位末端标记技术(TUNEL)检查CA3区细胞程序化死亡情况。结果预防组SE发生率为66.7%,明显低于非预防组(100%)(P<0.05);预防组SE潜伏期为(41.0±18.1)m in,明显长于非预防组的(21.5±8.2)m in(P<0.01)。SE后24 h,CA3区存活神经元数量和程序化死亡细胞数量在预防组和非预防组间差异无统计学意义(P>0.05)。结论预先给予姜黄素能抑制氯化锂-匹罗卡品诱导的SE,但无明显神经元保护作用,其机制和潜在的临床应用价值值得深入研究。
