Abstract :
Shea (Vitellaria paradoxa) is a Sapotaceae which leaves, roots and nuts butter are widely used in traditional medicine for the treatment of several health disturbances. Here the healing potential of its germinated nuts was demonstrated in vitro, through the antioxidant power of their crude/dialysed proteins and hydroalcoholic extracts; DPPH test was carried out therefore. Both proteins and hydroalcoholic extracts of germinated seeds reduced significantly DPPH, at various rates; hydroalcoholic extract recorded the best rate (86.30%). Crude (31.62%) and fractioned proteins (34%) registered less than the half of hydroalcoholic extracts inhibition rate. Ungerminated seeds crude and hydroalcoholic extract have also reduced the radical DPPH with values of 38% and 86.13% respectively. These results show that the protein and hydroalcoholic extracts of shea seed cakes could be validly exploited in the management or treatment of diseases due oxidative stress.
