BACKGROUND We conducted this investigation in order to examine the anti‐obesity and hypolipidaemic effects of Nelumbo nucifera seed ethanol extract ( NSEE ) in vitro and in vivo .METHODS To study the anti‐obesity effect of NSEE in vitro and in vivo , human pre‐adipocytes were treated with NSEE , and male Sprague–Dawley rats were fed with a normal diet and a high‐fat diet with or without NSEE , respectively.RESULTS In vitro treatment with NSEE resulted in inhibition of lipid accumulation and decreased expression of peroxisome proliferator‐activated receptor gamma ( PPARγ ), glucose transporter 4 ( GLUT4 ), and leptin in cultured human adipocytes, indicating that it inhibited the differentiation of pre‐adipocytes into adipocytes. Administration of NSEE resulted in significantly reduced body weight gain and adipose tissue weights in rats. Serum triglyceride and leptin level of the high‐fat diet + NSEE group was significantly lower, compared to the high‐fat group.CONCLUSION These results demonstrate an inhibitory effect of NSEE on adipogenesis. In addition, NSEE had a beneficial effect, reducing adipose tissue weights, ameliorating blood lipid profile, and modulating serum leptin level in rats fed a high‐fat diet. Therefore, we suggest that lotus seed has a potential to be developed as an effective agent against obesity‐related diseases. © 2013 Society of Chemical Industry
