Antihypercholesterolaemic influence of dietary tender cluster beans (Cyamopsis tetragonoloba) in cholesterol fed rats.

ABSTRACT

Background & objectives: Cluster beans (Cyamopsis tetragonoloba) are rich source of soluble fibre content and are known for their cholesterol lowering effect. The beneficial anti-hypercholesterolaemic effect of whole dietary cluster beans as a source of dietary fibre was evaluated in high cholesterol diet induced hypercholesterolaemia in experimental rats. Methods: Male Wistar rats (90-95 g) divided in six groups of 10 rats each were used. Freeze dried tender cluster beans were included at 12.5 and 25 per cent levels in the diet of animals maintained for 8 wk either on high (0.5%) cholesterol diet or basal control diet. Results: Significant anti-hypercholesterolaemic effect was seen in cluster bean fed animals, the decrease in serum cholesterol being particularly in the LDL associated fraction. There was also a beneficial increase in HDL associated cholesterol fraction. Hepatic lipid profile showed a significant decrease in both cholesterol and triglycerides as a result of feeding tender cluster beans along with high cholesterol diet. Interpretation & Conclusions: The present experimental results showed the beneficial hypocholesterolaemic and hypolipidimic influences dietary tender cluster beans in atherogenic situation. Studies in human need to be done to confirm the results.
