Antihyperlipidaemic effects of Eugenia jambolana fruit in diet induced hyperlipidaemic rats

To evaluate the antihyperlipidaemic effects of Eugenia jambolana fruit pulp in diet induced hyperlipidaemic rats and to compare them with Simvastatin.

An experimental randomised control study was conducted on seventy five male albino rats, divided into five groups labelled A, B, C, D and E with fifteen rats in each group. Group A was kept as normal control, groups B, C, D and E were given hyperlipidaemic diet for six weeks. In group B no further intervention was done, group C and group D were given ethanolic extract of Eugenia Jambolana and Simvastatin respectively for eight weeks. Group E was given combination of both for same duration. Serum total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and triglycerides were measured at zero, six and fourteen weeks.

At fourteenth week significant reductions in total cholesterol, low density lipoprotein cholesterol and triglycerides and a rise in high density lipoprotein cholesterol was observed in interventional groups C, D and E as compared to experimental hyperlipidaemic control group B (p < 0.05). There was no significant difference at baseline (zero weeks) serum total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and triglycerides of groups A, B, C, D & E; p > 0.24, p > 0.37, p > 0.89, p > 0.2, respectively. On sixth week, there was no significant difference between groups B, C, D and E (p > 0.05). However, 15 rats of group A had significant lower levels of cholesterol, high density lipoproteins, low density lipoproteins and triglycerides when compared to 60 rats of groups B, C, D and E (p < 0.05).

In male albino rats ethanolic extract of Eugenia Jambolana fruit pulp was as effective as simvastatin in lowering serum total cholesterol, low density lipoprotein cholesterol and triglycerides and increasing high density lipoprotein cholesterol.
