Abstract

The alginic acid or the salts thereof having average molecular weight of between about 5,000 -20,000 daltons and exhibiting intrinsic viscosity of between 1 - 20 measured by the Ubbelohde viscometer are provided. Most of the alginates have molecular weight of between 1,000 - 30,000 daltons. They are prepared form a high molecular weight alginic acid by means of decomposition, ultrafiltration and nanofiltration membran. they are of uses for prevention and treatment of hypertension, primary hyperaldosteronism and for reducing blood sugar.
