Abstract
Background
Parquetina nigrescens (Afzel) Bullock is a commonly used medicinal plant in African traditional medicine. The powdered roots and stems of the plant are taken with pap as a memory enhancer among the Yorubas of southwestern Nigeria. The mechanism by which scopolamine induces cognitive deficit mimics the pathogenesis of neurodegeneration in cognitive impairment. This study therefore, aimed at investigating the effect of the methanol stem extract of P. nigrescens on sub-chronically scopolamine-induced cognitive deficit in mice.
Method
Phytochemical screening was carried out on the extract using standard protocols. The oral median lethal dose (LD50) was estimated according to the Organisation for Economic Cooperation and Development (OECD) 425 limit test guideline. Doses of 250, 500, and 1000 mg/kg of the extract were used for the study. The elevated plus maze (EPM) and novel object recognition tests (NORT) were used to assess cognitive function. The brain tissue was assayed for the level of malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD) and acetylcholinesterase (AChE) activity.
Results
The plant extract contains phenolics, carbohydrates, tannins, saponins, and unsaturated sterols.The extract decreased the transfer latencies on days 7 and 8 against the scopolamine group in EPM and increased the discrimination index decreased by scopolamine in NORT. The methanol stem extract of P. nigrescens significantly (p ≤ 0.01) reduced MDA level; significantly (p ≤ 0.01) increased SOD activity; non-significantly increased GSH activity and the activity of AChE apeared not altered.
Conclusion
The methanol stem extract of P. nigrescens ameliorated sub-chronically scopolamine-induced cognitive deficit via antioxidant mechanism.
