IN VIVO EVALUATION OF ANTI-INFLAMMATORY AND ANALGESIC ACTIVITIES OF NIGELLA SATIVA SEED DURING GERMINATION
MOHAMMAD HAYATUL ISLAM, IFFAT ZAREEN AHMAD AND MOHAMMAD TARIQ SALMAN
Objective: The medicinal values of Nigella sativa have been mentioned in ancient literature as useful in disorders of inflammation. The present study investigates the anti-inflammatory and analgesic activities of methanol extract of Nigella sativa seed during different phases of its germination on Wistar rats. Methods: Seeds of N. sativa were grown in vitro in glass petri plates using multiple folds of damp filter paper. Complete plantlet with two leaves was obtained in 11 days. The acute anti-inflammatory activity of N. sativa extracts during different phases of germination was measured plethysmographically using kaolin as inflammatory agent, analgesic activity was measured by hot plate method, keeping indomethacin (10mg/kg b.w) as reference standard in both tests.
Results: All tested extracts of N. sativa (1gm/kg b.w) during different phases of germination showed significant reduction in paw oedema in comparison to control (P<0 .001="" 5th="" all="" among="" analgesic="" and="" anti-inflammatory="" day="" during="" effect="" extract="" extracts.="" germination="" hot="" in="" increased="" of="" on="" p="" plate="" reaction="" showed="" significant="" test.="" test="" tested="" the="" time="">
Conclusion: It may be concluded that extracts of N. sativa possess enhanced anti-inflammatory and analgesic activities during germination as compared to seed extract. High metabolic activity and higher contents of secondary metabolites expressed during germination might be responsible for this activity.
