Anti‐obesity activity of anthocyanin and carotenoid extracts from color‐fleshed sweet potatoes

The anti-obesity effects of anthocyanin and carotenoid extracts from color-fleshed potatoes were studied with 3T3-L1 cells in vitro and high-fat diet (HFD)-induced obese mice in vivo. Treatment of 3T3-L1 adipocytes with anthocyanin and carotenoid extracts, respectively, after differentiation induction significantly inhibited fat accumulation by 63.1 and 83.5%. Studies of adipogenesis inhibition showed that the anthocyanin extract acts at...
