Evaluation and Comparison of Trachyspermum ammi Seed Extract for Its Anti-inflammatory Effect

Aims and Objectives: The present study was aimed to evaluate the antiinflammatory effect of different seed extracts of Trachyspermum ammi at different doses.

Materials and Methods: Three different seed extracts were prepared through Soxhlet extraction method by using n-hexane, chloroform and methanol solvents. Acute toxicity test performed at dose of 400 mg/ kg, 800 mg/kg, 1600 mg/kg and 3200 mg/kg. Two different strengths of seed extracts (minimum therapeutic dose of 500 mg/kg and maximum therapeutic dose of 1000 mg/kg) were given to Wistar rats to measure anti-inflammatory activity through Carrageenan induced paw edema method.

Results: The standard drug diclofenac sodium was (percentage of inhibition of paw edema 29.68%) more effective as compared to test drug. When efficacy of all extracts compared with each other, n-hexane extract showed more anti-inflammatory effect (percentage inhibition of paw edema 22.21%) at maximum effective dose 1000 mg/kg.

Conclusion: Seed extracts of T. ammi showed anti-inflammatory activity by potentiating the neurotransmission of GABA and also by repression glutamate receptor.
