Abstract
Background: The aim of the current study was to investigate the scientific basis of the traditional application of Lophopetalum javanicum for measuring anti-inflammatory and analgesic activity and phytochemical screening.
Methods: Present study includes the preliminary screening of the phytochemical composition and in vivo analgesic and anti-inflammatory activity of methanolic extract of L. javanicum (MELJ). Hot-plate test and tail immersion method were used to investigate acute analgesic effects of L. javanicum, and the potency in inhibition of chronic inflammation in mice was tested by carrageenan-induced paw edema and formalin-induced edema method.
Results: One hour after the administration of carrageenan, rat’s paw was inflamed, and after treating it with 500 mg/kg dose, increase in the significant inhibitory effect on paw was observed. At the third hour after carrageenan injection, extreme inhibition (55.61%±0.015%; p<0.001) resulted by methanolic extract. By using hot plate method, it was found that L. javanicum increases pain tolerance time up to 17.89±0.079 min, whereas the compared standard’s interval was 21.48±0.397 min. In tail immersion method, the pain threshold was 3.02±0.074 (p<0.001) at 400 mg/kg by L. javanicum at 90 min of experiment.
Conclusions: This study manifested that the methanolic extract of L. javanicum is efficient in inhibiting pain mediators to release, and conceivably, this report should get priority while searching for a new analgesic and anti-inflammatory agent.
