Cardioprotective effect of new functional food containing salmon oil with motherwort oil extract

: Combination of fish oil with herbal oil extract can extend functional properties of the products. A new functional food of salmon oil with oil extract of motherwort (8:2) was developed and studied. Qualitative profiling was evidenced about presence of flavonoids and iridoids. Quantification of vitamins A (210±3 IU/g), Е (2.8±0.1 mg/g), D3 (12.2±0.4 IU/g) and PUFA (43.3±0.4%, incl. 9.4±0.1% of omega-3 and 33.9±0.1% of omega-6) was done by modern methods. The developed product was found nontoxic (LD50>15 000 mg/kg b.w., intragastriсally, LD50>3000 mg/kg b.w., intraperitoneal). The 14 days intragastric administration of product to the rats (initial b.w. 200-250 g) at the doses of 2340 and 1170 mg/kg b.w. significantly increased the left ventricular pressure after ischemia comparing with control, and normalized the contraction and relaxation of the left ventricle. Biochemical data confirmed the decrease of aspartate amino transferase and creatine kinase activity in rats treated at all experimental doses. Application of fish oil combination with motherwort oil extract is promising for development of new functional foods with cardio protective properties.
