abstract = "Aronia melanocarpa (AM) is a medicinal plant commonly named black chokeberry and investigated for wide-array of health-promoting characteristics. The beneficial properties of AM on human health are attributed to high content of non-nutritional phytochemicals i.e. polyphenols. The AMJ corresponded to commercial aronia juice product, available on the Serbian market. A commercial product used has been registered as dietary supplement by Serbian Ministry of Health, under the trade name "Aronia Anti-Oxi" (515-04-1339/2011-04).
The animals were devided in 2 groups of 8 animals each, to receive ad libitum either full polyphenol aronia dose (AMJ), and polyphenol- lacking placebo beverage (PLB).
The animals were kept in groups of 4 per cage, under controlled conditions (room temperature 23-25°C, 12 h light-dark cycle, food and water ad libitum). All animal procedures were in compliance with Directive 2010/63/EU on the protection of animals used for experimental and other scientific purposes, and approved by the Ethical Committee for the Use of Laboratory Animals of the Institute for Biological Research "Siniša Stanković".
The extraction and preparation of FA esters and GC analyses were performed (Folch 1957). Methyl-ester derivatives formed from isolated liver phospholipids fraction were separated by GC (Shimadzu Co, Tokyo, Japan)
Our results showed decreasing in stearic acid (p<0.01), increasing in vaccenic acid (p<0.001) as well as MUFA(p<0.05). Dihomo-gama- linolenic (n-6) acid was increased (p<0.05) while arachidonic acid (n-6) was decreased (p<0.05). n-6/n-3 ratio was decreased but not significantly. Liver enzyme activities were significantly different for elongase (p = 0.009) and D5D enzyme (p = 0.015), due to the decreasing effect of aronia juice consumption in comparison with control.
Stronger effect of aronia juice in liver, as a primary site of FA metabolism and through the decreasing in arachidonic acid, as well as decline in FA metabolic enzymes indicates favorable lipid-metabolism related properties of AMJ consumption.",
