ABSTRACT
The number average molecular weights of five fractionated samples of pomelo pectin were determined osmometrically in aqueous solution. The values of Mn ranged from 4.74?104 to 1.83?144 for different fractions.From the data of osmotic pressure and intrinsic viscosity, the [?]-M relation obtained is[?]3.23?10-7M1.75in 0.9% NaCl solution of pH 4.83 at 37℃.
