A comparative study on composition and antioxidant activities of supercritical carbon dioxide, hexane and ethanol extracts from blackberry (Rubus fruticosus) growing in Poland

摘要

BACKGROUND: Large quantities of blackberry seeds are produced as a pomace during the processing of juice and jam production; thisby-product is a very interesting rawmaterial both foroil manufacturingandas a source of bioactive compounds. In thiswork the composition, yield and antioxidant activity of three types of Rubus fructicosus pomace extracts isolated by liquid extraction using solvents of different polarity, as well with supercritical CO2 fluid extraction have been compared.
