Asparagus racemosus Wild root has been used traditionally in Ayurveda for the treatment of diarrhoea and dysentery. However, the claims of Ayurveda need to be validated by a suitable experimental model. Therefore, the present study was undertaken to evaluate the effect of ethanol and aqueous extracts of Asparagus racemosus for its antidiarrhoeal potential against several experimental models of diarrhoea in Albino Wistar rats.
The antidiarrhoeal activity of ethanol and aqueous extracts of Asparagus racemosus root was evaluated using castor oil-induced diarrhoea model in rats. Further, we evaluated the effect of ethanol and aqueous extracts on gastrointestinal tract motility after charcoal meal administration and PGE2 induced intestinal fluid accumulation (enteropooling). Loperamide was used as positive control.
The plant extracts showed significant (P < 0.05) inhibitor activity against castor oil induced diarrhoea and PGE2 induced enteropooling in rats when tested at 200 mg/kg. Both extracts also showed significant (P < 0.001) reduction in gastrointestinal motility in charcoal meal test in rats.
The results point out the possible anti-diarrhoeal effect of the plant extracts and substantiate the use of this herbal remedy as a non-specific treatment for diarrhoea in folk medicine.
印度人参(Asparagus racemosus Wild)根在阿育吠陀传统医学中一直被用于治疗腹泻和痢疾。然而,阿育吠陀传统医学的说法需要通过合适的实验模型来验证。因此,本研究旨在评估印度人参乙醇提取物和水提取物对白化Wistar大鼠几种腹泻实验模型的止泻潜力。
采用蓖麻油诱导的大鼠腹泻模型评估印度人参根乙醇提取物和水提取物的止泻活性。此外,我们在给予炭末后评估了乙醇提取物和水提取物对胃肠道蠕动的影响,以及对前列腺素E2诱导的肠液积聚(肠内积液)的影响。洛哌丁胺用作阳性对照。
当以200mg/kg进行测试时,植物提取物对蓖麻油诱导的大鼠腹泻和前列腺素E2诱导的大鼠肠内积液显示出显著(P<0.05)的抑制活性。两种提取物在大鼠炭末试验中也显示出胃肠道蠕动显著(P<0.001)降低。
结果指出了植物提取物可能具有的止泻作用,并证实了这种草药疗法在民间医学中作为腹泻非特异性治疗方法的应用。
