Vasorelaxant and Hypotensive Effects of Jaboticaba Fruit (Myrciaria cauliflora) Extract in Rats

Figure 2

The relaxant effect of the HEMC in isolated rat thoracic artery. Cumulative concentration-response curves for the HEMC (a) or acetylcholine (Ach) (b), a well-known endothelium-dependent vasorelaxant (positive control), in rings of thoracic artery with endothelium (E⁺, ) and without endothelium (E⁻, ) precontracted with phenylephrine (0.1 μM). The data points represent the mean ± SEM of the relaxing effect expressed as a percentage. Significant difference (E⁺ versus E⁻).
