The selected plant extract produced concentration dependent percentage inhibition of antioxidant activity. The ethanolic extract of Leonotis nepetifolia showed low activity on hydroxyl and DPPH radical and moderate effect on nitric oxide radical. The results of the present study suggest that the tested ethanolic extract have antioxidant activity and/or free radical scavenging activity. Preliminary phytochemical studies of the extract shows the presence of flavonoids and phenolic compounds, therefore, the antioxidant activity might be due to the presence of flavonoids and phenolic compounds in...

From the observations made both extracts of whole plant of Leonotis nepetiifolia was found to show a potent anthelmintic activity. Ethanolic extract of at 75 mg/ml concentration shows paralysis at 52 min and death 69 min, while aqueous extracts show paralysis at 69 min and death 90 min by the earth worm Pheretima posthuma. Among two extracts aqueous extracts show least anthelmintic activity. The reference drug Albendazole exhibited the same at 45 min and 61 min respectively. Albendazole exhibits anthelmintic activity by blocking glucose uptake and depletion of glycogen stores in test...
