Abstract

Water-soluble chitosan-indole-3-propionic acid conjugates useful as active constituents in pharmaceutical as well as cosmeceutical and agricultural applications are described.

Claims1

Dependent claims

A water-soluble chitosan-indole-3-propionic acid conjugate produced by the method comprising:

1) adding indole-3-propionic acid to water, 2) adding chitosan to the indole-3-propionic acid solution in pH ranging from pH 1.0 to pH 6.9 to form a chitosan-indole-3-propionic acid conjugate, 3) stirring the chitosan-indole-3-propionic acid conjugate, 4) lyophilizing the chitosan-indole-3-propionic acid conjugate of step 3, to produce a stable powder.

Dependencies are inferred from the claim text.
