Rapeseed oils are commonly used as edible oil in rural and urban areas in Bangladesh. This study used various rape seeds like mustard, rai and canola oils to investigate the effect on lipids and cardio-hepatic enzymes in experimental rats. Body weight, food efficiency ratio (FER), serum lipids and cardio hepatic enzymes were measured in this study. Body weights were reduced in fried rai (37.67%) and mustard oils (33.18%) in comparison with the control and canola oils (19.78%). While both wild and hybrid mustard oils (20.97 and 24.72%, respectively) and rai oils (23.08 and 24.76%, respectively) also decreased the body weight. FER of rats was high in control group (0.11%) and lower in both fried mustard and rai oils (0.05%). Total cholesterol (TC), triglycerides (TG) and low density lipoprotein (LDL) were significantly high in fried rai (56.11, 144.1 and 16.25 mg/dl, respectively) and fried mustard oils (55.03, 142.01 and 14.68 mg/dl, respectively) while the lowest were in control (39.04, 90.02 and 7.07 mg/dl, respectively) and canola oils (40.46, 95.06 and 7.80 mg/dl, respectively). On the contrary, high density lipoprotein (HDL) was raised in control group (28.06 mg/dl) and decreased in fried rai and mustard oils (11.12 and 12.07 mg/dl, respectively). This result also showed that cardio hepatic enzymes like creatine kinase-MB (CK-MB), aspartate amino transferase (AST) and alanine amino transferase (ALT) were increased in fried rape seeds than control and canola oils. Fried mustard oils were more detrimental than wild mustard oils and canola oils due to the highly concentrated erucic acids.
Key words: Mustard oils, canola, lipid profiles, aspartate amino transferase (AST), alanine amino transferase (ALT), creatine kinase-MB (CK-MB).
