The whole plant of Biophytum petersianum was extracted with a mixture of water – alcohol (1:1) to evaluate its relaxant effect on aorta rings. In isolated Wistar rat tissue, the hydro-ethanolic extract (0.1; 0.25 and 0.5 mg/ml) non-competitively antagonized calcium chloride and high-K + - induced aorta contractions in a concentration-dependent manner. Moreover, the inhibition of noradr...
