Abstract
To investigate the effect of n-3 fatty acid from Bokbunja (Rubus coreanus Miq.) seed oil (BSO), we examined improvement of plasma triglycerides and cholesterol in vivo. Five-week-old ICR mice were divided into five groups of six mice each; Control, high fat diet (HFD) control (negative control), salmon oil control (positive control, HFD+commercial n-3 fatty acid), and BSO¡¡experimental groups (HFD+1 g/60 kg BW/d, HFD+2 g/60 kg BW/d). After 4 weeks of BSO treatment, we measured serum triglyceride and cholesterol levels. The levels of low-density lipoprotein/very-low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, and total cholesterol were significantly (P<0.05) reduced in the group fed BSO at 2 g/60 kg BW/d compared to the negative control. Levels of triglycerides, which are similar to cholesterol, were also significantly (P<0.05) reduced in the same group. To investigate further, we tested blood coagulation parameters. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were not significantly different among the five groups according to BSO. However, the 2 g/60 kg BW/d BSO group treated with PT and aPTT showed a tendency to live longer than the negative control. Taken together, BSO might improve blood homeostasis mediated via hypo-lipidemic and anti-coagulation activities.
