Effect of P. jiringa fruit rinds extracts on microvessels outgrowth in rat aortic rings. The rings were treated with (A) 1% DMSO, (B) 10 μg/ml EtOH extract, (C) 10 μg/ml EW extract and (D) 100 μg/ml suramin as a positive control. (E) Dose dependent relationship of the (i) EtOH and (ii) EW extracts on the microvessels outgrowth of the explants. The data was represented as means of three experiments (n=3), error bars equal ± SD. *P < 0.05, ** P <0.01 and *** P < 0.001.
