Negatively charged polysaccharide derivable form Aloe Vera

摘要

A new composition of matter is provided comprising negatively charged polysaccharides which can be derived from Aloe vera and a process to prepare that composition of matter by sub fractionation of an extract of Aloe vera, passing the formed subfraction over a positively charged column and eluting the same with a salt solution. Optionally the Aloe vera is pre purified over a Sephadex G-25 column. This composition of matter and also the extract comprising the same which is formed after pre purification is useful as a food supplement or in dietary foods, for use in personal care and in cosmetics, especially to prevent an infection with Helicobacter pylori.
