PURPOSE: A polyelectrolyte complex useful as a lipid depressant, comprising a complex of a cationic dextran derivative of a specified nitrogen content with a polyuronic acid. n CONSTITUTION: A polyelectrolyte complex of a cationic dextran derivative of a nitrogen content of about 0.5W12%, said cationic dextran derivative being represented by formula I, with a polyuronic acid selected from among pectin, pectic acid, hyaluronic acid and gum arabic. In formula I, R is H or a group of formula II (wherein R 1 and R 2 are each a lower alkyl, R 3 is H or a nitrogen- containing group of formula II) and m is 1, 2 or 3, when R 3 is a nitrogen- containing group of formula II, R 3 in this nitrogen-containing group is H, at least one of R's is a nitrogen-containing group of formula II, and n is 2W150,000. n COPYRIGHT: (C)1986,JPO&Japio |
