摘要: A two-step supercritical fluid extraction process of rosemary leaves, on a pilot plant scale, is proposed to divide the oleoresin into two fractions with different antioxidant activities and essential oil composition. Rosemary leaves were extracted by using conditions pressure temperature as well for fractionation extracts. Conditions can be tuned selectively extract one fraction almost no residual aroma. In present investigation, was exhaustively studied in terms activity measurements chemical An LC-MS method adapted perform analysis identification compounds responsible Different order correlate obtained.
