ABSTRACT
The research was undertaken to determine the effect of Jerusalem artichokes tuber flour - Jerusalem artichoke flour on total cholesterol content, concentrations of HDL, LDL+VLDL lipoproteins and triglycerides in blood of experimental rats. The animals were divided into four experimental groups and fed for 24 days with mixtures containing various proportions of Jerusalem artichoke flour. On the last day of the experiment the rodents were anaesthetised and blood was sampled directly from the heart. Total cholesterol, HDL and triglycerides were assayed in blood serum. The content of LDL+ VLDL lipoproteins were calculated from the difference between total cholesterol and HDL lipoproteins. A declining tendency was observed for total cholesterol level and LDL+VLDL lipoproteins when the diet was supplemented with the Jerusalem artichoke flour. On the other hand the amount of triglycerides decreased statistically significantly in blood serum of animals fed diets with 10% and 15% supplement of Jerusalem artichoke flour.
Key words: Jerusalem artichoke flour, lipid profile, rats.
