Abstract

This study is aimed to clarify the mechanism of wolfberry fruit and leaf extract’s regulation of lipid metabolism, and to provide the necessary theoretical basis for the possible uses of wolfberry fruit extract as drugs improving lipid metabolism. We have investigated the effects of wolfberry extract on the proliferation and differentiation as well as lipid metabolism of preadipocytes on cell level, and have evaluated the influences of wolfberry extract on obese mice body weight, oral glucose tolerance and blood glucose. The comparison between the effects of different parts of wolfberry and the combination of experiments of cell and animal level are done for the first time. Results show that: neither wolfberry fruit nor wolfberry leaf has toxicity on 3T3-L1 preadipocytes; wolfberry extract can promote adipocyte differentiation and intracellular lipid accumulation, while wolfberry leaf does not have such effects; fruit extract can improve the C/EBPα, PPAR-γ gene expression levels and activate the transcriptional activity of PPAR-γ, while leaf does not have such effects; both wolfberry fruit and wolfberry leaf can reduce the blood glucose and improve the oral glucose tolerance of obese mice, and wolfberry fruit has a stronger effect, but in the meanwhile they also increase the mice’s body weight. Based on the results above, we can conclude that wolfberry fruit extract ingredients can regulate glucose and lipid metabolism to some extent. Thus, it has the potential to work as a kind of medicine to improve lipid metabolism and to cure type 2 diabetes.
