    • Figure 1. 

      Effect of wild lettuce and African eggplant leaves extract on (a) lungs and (b) kidney ACE activity in L-NAME induced hypertension in rats. Values represent mean ± standard deviation (n = 6). * Significantly different when compared normotensive with hypertensive (p < 0.05). ** Significantly different when compared wild lettuce and African eggplant leaves extract-treated hypertensive with hypertensive (p < 0.05).

    • Figure 2. 

      Effect of wild lettuce and Africa eggplant leaves extract on the (a) heart and (b) kidney arginase activity in L-NAME induced hypertension in rats. Values represent mean ± standard deviation (n = 6). * Significantly different when compared normotensive with hypertensive (p < 0.05). ** Significantly different when compared wild lettuce and African eggplant leaves extract-treated hypertensive with hypertensive (p < 0.05).

    • Figure 3. 

      Effect of wild lettuce and Africa eggplant leaves extract on the (a) heart and (b) kidney acetylcholinesterase (AChE) activity in L-NAME induced hypertension in rats. Values represent mean ± standard deviation (n = 6). * Significantly different when compared normotensive with hypertensive (p < 0.05). ** Significantly different when compared wild lettuce and African eggplant leaves extract-treated hypertensive with hypertensive (p < 0.05).

    • Figure 4. 

      Effect of wild lettuce and Africa eggplant leaves extract on (a) plasma, (b) heart, (c) kidney and (d) lungs Nitric oxide level in L-NAME induced hypertension in rats. Values represent mean ± standard deviation (n = 6). * Significantly different when compared normotensive with hypertensive (p < 0.05). ** Significantly different when compared wild lettuce and African eggplant leaves extract treated hypertensive with hypertensive (p < 0.05).

    • Figure 5. 

      Effect of wild lettuce and Africa eggplant leaves extract on the (a) heart, (b) kidney and (c) lungs total thiol level in L-NAME induced hypertension in rats. Values represent mean ± standard deviation (n = 6). * Significantly different when compared normotensive with hypertensive (p < 0.05). ** Significantly different when compared wild lettuce and African eggplant leaves extract-treated hypertensive with hypertensive (p < 0.05). β Not significantly different when compared wild lettuce and African eggplant leaves extract-treated hypertensive with hypertensive.

    • Figure 6. 

      Effect of wild lettuce and African eggplant leaves extract on malondialdehyde level in (a) plasma, (b) heart, (c) kidney and (d) lungs of L-NAME induced hypertensive rats. Values represent mean ± standard deviation (n = 6). * Significantly different when compared normotensive with hypertensive (p < 0.05). ** Significantly different when compared wild lettuce and African eggplant leaves extract-treated hypertensive with hypertensive (p < 0.05). β Not significantly different when compared wild lettuce and African eggplant leaves extract-treated hypertensive with hypertensive.
