- Abstract
The present-day preoccupations for an alimentation which, besides the characteristic of physiological necessity, should also play a protective rote make necessary the development of some protective character quantification models as diversified as possible. There have been noticed significant connections between the values marked with (d(O,A)) and representing the position of a stability point and the reductive power primary indicators of some analyzed vegetal samples. Its position will be expressed by the Euclidian distance to towards the origin of the axe system expressed by the relation: d(O,A)= ((ab)1/b+1)² + (a/(ab)b/b+1)²)1/2 . The coefficients a and b are to be determined by using the classic statistic methods. The values of the correlation coefficients for some particular types of functions proposed as link model between the two series of data (bleaching time, d(O,A)) are presented. The bleaching time during some reactions which lead to the color change of some oxidant substances in the presence of the analyzed vegetal samples in initially fixed quantities, is a primary indicator of their reductive power. Its use is not topical anymore because of the subjective interpretations it offers. Nevertheless, the connections with the above mentioned indicator lead to new hypotheses regarding the possibility of promoting some numeric indicators of the total antioxidant activity of some substances.
