The hypolipidaemic effect of Gum Tragacanthin diet induced hyperlipidemia in rats.
Pak J Pharm Sci Jan ;12(2):33-9.

Previous research indicated that fiber in the diet of men lowers plasma lipid and LDL cholesterol concentration. To further study the lipid lowering effect of fibre, we conducted an animal study using rats with diet induced hyperlipidaemia. Rats were randomly assigned to one of the three experimental diets. Two of the diets contained cholesterol and choice acid to induce hyperlipidaemia, the fiber source in the hyperlipidaemic diet was gum tragacanth (5%). The rats consumed one of the three diets ad libitum for 4 weeks before they were killed. Plasma LDL cholesterol and total cholesterol concentrations were significantly higher in the hyperlipidaemic group than in the non hyperlipidaemic control group. A marked improvement in the plasma LDL cholesterol and total cholesterol concentration was observed in the rats that were fed hyperlipidaemic diet containing grum tragacanth. No significant difference in the plasma triglyceride concentration was detected in the three groups. Plasma HDL concentration was significantly higher in the non-hyperlipidaemic group than in the hyperlipidaemic group than. Addition of gum tragacanth to the hyperlipidaemic diet significantly improved the plasma HDL concentration in the hyperlipidaemic rats. These results suggest that fiber from gum tragacanth lowers plasma cholesterol and LDL in hyperlipidaemia. Gum tragacanth could be useful adjunct to the dietary management of hyperlipidaemia.
