Abstract
Flavour symmetry breaking is introduced in the approximate formula for quark mass reported earlier. We use SLAC-MIT as well as NMC data to e stimate the up, down and strange quark masses from structure functions . Using the approximate Q2 evolutions of Altarelli-Parisi equations, w e also estimate its perturbative and nonperturbative components.
