Abstract

The number of methods to measure antioxidants in botanicals, foods, nutraceuticals and other dietary supplements are increased considerably in the last 10 years. However most techniques require long experimental times and high costs to determine antioxidant capacity of hydrophilic or lipophilic compound in a food mixture. By means of a photochemiluminescence method, we assessed the Integral Anti- oxidant Capacity (IAC) which represents the sum of the antioxidant capacity of hydrophilic and lipophilic antioxidants. In this study the IAC of extracts from Adansonia digitatata (i.e. red fiber, fruit pulp and leaves), was assessed in comparison to those deriving from other natural sources of antioxidants (i.e. orange, kiwi, apple and strawberry). When compared, IAC values for the examined product resulted as follows: Adansonia digitata red fibre >>> Adansonia digitata fruit pulp >> Adansonia digitata fresh leaves >> Adansonia digitata seeds > Adansonia digitata radix cuticle > orange fresh pulp >> strawberry fresh fruit pulp > Adansonia digitata radix > bilberry fresh pulp >> kiwi fruit pulp. Results clearly indicate the interesting antioxidants properties of Adansonia digitatared fibre, in particular the IAC value of baobab red fibre was 66 time higher than that of orange pulp, with value of 1617.3 lmol/g and 24.3 lmol/g, respectively.
