The effect of the methanolic fraction of Pluchea indica Less. root extract was evaluated on various models of inflammation and ulcer in vivo to assess the role of P. indica on the 5-lipoxygenase pathway of prostaglandin synthesis. Studies presented here reveal significant antiinflammatory activity of the fraction on Arachidonic acid, Platelet activation factor and Compound 48/80-induced paw oedema. There was significant inhibition of spontaneous as well as compound 48/80-induced histamine release from mast cells. Ulcer studies revealed significant protective action of the fraction on indomethacin, alcohol and indomethacin-alcohol induced ulceration. There was significant decrease of gastric volume and acidity in pylorus ligated rats. Studies also showed, significant protective action of the same on gastric mucosa.

The role of chloroform fraction of Calotropis procera root extract on different experimental ulcer models in rats was investigated. The extract demonstrated significant anti-ulcer activity against aspirin, indomethacin, ethanol, indomethacin + ethanol, or stress-induced ulcerations. Significant inhibition of gastric secretory volume and total acidity in pylorus ligated rats were observed to occur with the extract. It was also observed that the root extract significantly inhibited arachidonic acid metabolism induced by soyabean lipoxygenase. The results suggest that the anti-ulcer activity of the extract might be attributable to the inhibition of 5-lipoxygenase (5-LO).
