Evaluation of Antiinflammatory Activity of Ethanol Extract of Fruit.

OBJECTIVES

In recent times, the use of natural remedies, which are rich in varieties of vitamins and flavonoids, for treatment of inflammation has increased substantially. These natural remedies are expected to be safe and economical when compared with other conventional allopathic drugs. Thus, existing research investigated the anti-inflammatory effect of fruit (NNF), in view of estimating its traditional and pharmacologic use against disorders associated with pain and inflammation.

MATERIALS AND METHODS

To estimate the antiinflammatory effect of NNF, carrageenan-induced paw edema method was employed with equally distributed (n=7) Wistar male rats (N=35). The paw edema was measured by volume displacement method with plethysmometer.

RESULTS

The NNF extract significantly reduced the inflammation of the paw and decreased the edema volume in rats administered carrageenan at all doses from the 3 to 5 hour when compared to control, whose maximum percent reduction of edema was estimated as 100 mg/kg dose (that is, 73.92% at the 5 hour after administration of carrageenan).

CONCLUSION

NNF exhibited a strong antiinflammatory effect, due to its phytochemical constituents, including flavonoids, saponins, and tannins, all of which synergistically exert inhibitory effects on arachidonic acid metabolism, neutrophil degranulation, and enzyme systems that promote cell proliferation and regulation of complement system. However, more preclinical and clinical evaluations are mandatory to validate these findings.
