Cyanidin-3-rutinoside (C3R), a naturally occurring anthocyanin, possesses anti-oxidant, anti-hyperglycemic, anti-glycation and cardioprotective properties. However, its mechanisms responsible for anti-hyperlipidemic activity have not been fully identified. The aim of the study was to investigate the lipid-lowering mechanisms of C3R through inhibition

An acid lipase was purified from rabbit liver lysosomes by, in sequence, osmotic treatment of the lysosomal fraction, Sephadex LH-20, DEAE-Sephadex A-50, Bio-Gel A-5m, hydroxyapatite and, finally, Sephadex G-200 column chromatography. The substrate was 4-methylumbelliferyl oleate. The enzyme was solubilized
