The combined influence of maturation, ripening and climate periods on French West Indies (FWI) bananas, Musa Cavendish, bioactive compounds profile was studied. The polyphenol content of the 400 dd bananas remained unchanged, while the 600 and 900 dd bananas exhibited a significant polyphenol increase during ripening (p<O.OS). Furthermore, the results showed that although dopamine was deterrnined as the highest polyphenol in the banana peels during the green developmental stage and ripening, its kinetic differed from the total polyphenol profile. Together ours results showed that this matrix of choice (maturation, ripening and climate may allow selection of Musa Cavendish status for optimal concentration in identified compounds with human health relevance. Indeed, this is the case of dopamine, a vasoactive mediator, which is dependent on physiological stages, ripening and climate. Thus, our work has demonstrated that the banana totum showed a dose-dependent contracture effect on aortic which was less powerful than the one recorded for reference compounds at lower concentrations. Nevertheless it was significant. In the same conditions, it was demonstrated that prazosin modifies the effect of banana contracture inhibiting it competitively. Receptor alpha-I adrenergic vascular plays a role in the vasoconstrictor effects of bananas. The study of ulcers through inhibition! non inhibition of Helicobacter pylori growth after addition of polar and apolar banana extracts indicated the role of Musa cavendish as a non-inhibitor of Heiicobacter pylori growth
