Comparative evaluation of antiinflammatory potential of fixed oil of different species of Ocimum and its possible mechanism of action.
Ocimum sanctum fixed oil and linolenic acid found to possess significant antiinflammatory activity against PGE2, leukotriene and arachidonic acid-induced paw edema. The other species of Ocimum, viz. O. basilicum and O. americanum also containing linolenic acid in varying proportions, also showed significant inhibition of edema against carrageenan, PGE2, leukotriene and arachidonic acid-induced paw edema. The fixed oil of O. basiliaum containing maximum percentage of linolenic acid showed higher protection. The results suggests that linolenic acid percent in the fixed oils of different species of Ocimum has the capacity to block both the cyclooxygenase and lipoxygenase pathways of arachidonate metabolism and could be responsible for the antiinflammatory activity.
