Abstract:
OBJECTIVEThe UF process of model systerm of Huanglian Jiedu decoction is researched in the study to lay a foundation for the exploring of the substance foudation of membrane fouling, and for the the optimal design of membrane technology in the production of Chinese drugs preparation.
METHODUsing the membrane flux, fouling degree of membrane, preserving degree and adsorption capacity of effective materials as guide line, trying to find out the influence of macromolecule materials on small molecules in Huanglian Jiedu decoction.
RESULTThe two small molecules berberine and gardenoside in Huanglian Jiedu decoction have high permeation rate. But for the reasons of interaction of macromolecule, the permeation rate of small molecules reduced greatly, membrane fouling and membrane flux declined intensify.
CONCLUSIONStarch and pectin are the two main macromolecule materials in Huanglian Jiedu decoction which cause membrane fouling and flux falling.
