- چکیده:
- چکیده انگلیسی: Objective: Premna integrifolia Linn (Family: Verbenaceae) synonym of Premna serratifolia has tremendous medicinal value. Preliminary pharmacological studies were performed on the methanolic extract of Premna integrifolia (MEPI) bark to investigate neuropharmacological, analgesic, and anti-inflammatory activities.
Materials and methods: Neuropharmacology study was done by open field and hole cross test whereas acetic acid writhing test and formalin induced pain was done for analgesic activity of MEPI. Carrageenan induced inflammatory model was considered for anti-inflammatory activity evaluation.
Results: A statistically significant (p<0.05) decrease in locomotor activity was observed at all doses in the open-field and hole-cross tests. The extract significantly (p<0.05) and dose dependently reduced the writhing reflex in the acetic acid-induced writhing test as well as licking response in the formalin induced inflammatory pain. At 200 mg/kg body weight dose, MEPI showed 71.16% inhibition in carrageenan induced anti-inflammatory activity.
Conclusion: The finding of this study suggests that MEPI will provide scientific support for the use of this species in traditional medicine.- انتشار مقاله: 13-06-1392

- چکیده:
- چکیده انگلیسی: Objective:The present study was designed to evaluate the antioxidant, analgesic, and anti-inflammatory activities ofthe methanolic extract of Piper betle leaves (MPBL).
Materials and Methods: MPBL was evaluated for anti-inflammatory activity using carrageenan-induced hind paw edema model. Analgesic activity of MPBL was evaluated by hot plate, writhing, and formalin tests. Total phenolic and flavonoids content, total antioxidant activity, scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, peroxynitrate (ONOO-) as well as inhibition of total ROS generation, and assessment of reducing power were used to evaluate antioxidant potential of MPBL.
Results: The extract of MPBL, at the dose of 100 and 200 mg/kg, produced a significant (p<0.05) increase in pain threshold in hot plate method whereas significantly (p<0.05) reduced the writhing caused by acetic acid and the number of licks induced by formalin in a dose-dependent manner. The same ranges of doses of MPBL caused significant (p<0.05) inhibition of carrageenan-induced paw edema after 4 h in a dose-dependent manner. In DPPH, ONOO-, and total ROS scavenging method, MPBL showed good antioxidant potentiality with the IC50 value of 16.33±1.02, 25.16±0.61 , and 41.72±0.48 µg/ml, respectively with a significant (p<0.05) good reducing power.
Conclusion: The findings of the study suggested that MPBLhas strong analgesic, anti-inflammatory, and antioxidant effects, conforming the traditional use of this plant for inflammatory pain alleviation to its antioxidant potentiality.
