Abstract

To investigate the efficacy of extract of Ginkgo Biloba seeds in high fat diet (HFD) in mice, the Ginkgo Biloba seeds extract (GSE) was orally administered to mice with a HFD at 300 mg/kg/day for 4 weeks. Our results show that GSE significantly inhibited fat accumulation. Moreover, GSE markedly reduced the final body weight with a decrease in epididymal adipose tissue mass and adipocyte size compared with the untreated HFD-induced group. Additionally, GSE ameliorated serum high-density lipoprotein cholesterol levels. The results show that Ginkgo Biloba seeds possesses hypocholesterolemic effect through down regulating lipid metabolism. Further studies are required in this area to strengthen the anti-obesity effects of GSE with active component, and it can be used a pro-drug instead of whole extract.
