Due to high contents of biologically active compounds fruits of rose hip (Rosa rugosa) prove very profitable for human being high antioxidation activity. These was received concentrates from fruits of rose hip (Rosa rugosa) by methods: vacuum's condensation and cryoconcentration and it compared these condensed environments in respect of chemical composition and antioxidant activity with concentrate originated from company AGRICO S.A. Researches exerted that cryoconcentration method allows better activity of antioxidants compounds than vacuum's condensation method. Total concentration of chemical antioxidants in a commercial concentrate was about 9 percent higher in comparison to juice after cryoconcentration and was about 30 percent higer in comparison to juice vacuum's condensation. Antioxidant activity of compressed juices was at approximated level
