Abstract

Objective: Gongronema latifolium (Asclepiadiaceae) is used as bitter spice or flavouring agent in many traditional Nigerian dishes. It is well known for medicinal and nutritional purposes like anti-hyperglycemic, anti-oxidant, antitussive and widely distributed in the southeastern states of Nigeria. Objective of present study was to evaluate the anti-hyperglycemic and anti-oxidant effect of the methanol extract of Gongronema latifolium leaves.


Methods: The methanol extract of G. latifolium at doses of 250 and 500 mg/kg were studied for anti-hyperglycemic effect in alloxan-induced hyperglycemic rats. The variation in blood glucose level in normal and experimental rats on 0, 7, 14 and 21 days of treatment has also been recorded. The effect of different treatment on body weight of rats was also determined. The antioxidant properties of the extracts as determined by the DPPH free radical scavenging assay.


Results: Treatment with G. latifolium extract showed signs of recovery as comparable with the standard drug glibenclamide (0.25 mg/kg). The result showed that G. latifolium extract caused a concentration dependent percentage increase of antioxidant activity.


Conclusion: Study concludes that methanol leaf extract of G. latifolium possesses significant anti-hyperglycemic and anti-oxidant activities.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
