Berries of Aronia melanocarpa (chokeberry) are known to be a rich source of biologically active polyphenols. In the present study, the effects of seven anti-adipogenic polyphenolic phytochemicals isolated from A. melanocarpa methanol extract on adipogenic transcription factors were investigated. Amygdalin and prunasin were found to inhibit 3T3-L1 adipocyte differentiation by suppressing the expressions of PPAR&gamma: (peroxisome proliferator-activated receptor &gamma:), C/EBP&alpha: (CCAAT/enhancer binding protein &alpha:), SREBP1c (sterol regulatory element binding protein 1c), FAS (fatty acid synthase), and aP2 (adipocyte fatty-acid&ndash:binding protein). A. melanocarpa extract-treated (100 or 200 mg/kg/day on body weight) high fat diet (HFD)-induced obese mice showed significant decreases in body weight, serum triglyceride (TG), and low-density lipoprotein cholesterol (LDLC) levels and improved insulin sensitivity as compared with HFD controls. This research shows A. melanocarpa extract is potentially beneficial for the suppression of HFD-induced obesity.
