We investigated the effects of the prenylated flavonoid-standardized extract (PFE) from the seeds of Psoralea corylifolia L. on countering obesity, which increases energy expenditure and stimulates thermogenesis in subcutaneous white adipose tissue (sWAT) and brown adipose tissue (BAT). For 12 weeks, C57BL/6 mice were fed a controlled high-fat diet (HFD) or HFDs with 0.2% or 0.5% w/w PFE. In vitro, the differentiation of 3 T3-L1 cells was used to elicit thermogenesis in the presence of PFE. PFE obviously reduced body weight and fat mass in a dose-dependent manner, increased energy expenditure, improved insulin sensitivity, and prevented hepatic steatosis by increasing lipid oxidation and secretion in HFD-fed mice. Moreover, PFE induced clear browning in sWAT, significantly increased phosphorylation of AMPKα1/2 and p38, increased BAT activity and the differentiation of 3 T3-L1 by increasing the expression of uncoupling protein 1 and other thermogenic genes. Our study showed that PFE prevented obesity by increasing browning and activating thermogenic genes in sWAT and BAT, improving glucose homeostasis, and protecting hepatic steatosis.
